The immune system does not hate the thing it rejects. Hatred is a human emotion, complex and theatrical, requiring narrative and moral judgment and the elaborate architecture of resentment. The immune system simply recognizes, identifies, responds. Non-self is non-self. The recognition is molecular, mechanical, indifferent to the suffering that the response produces in the individual who is the target of the response, and the suffering is real but incidental, a byproduct of a process that has no opinion about the suffering, the way a fever has no opinion about the pain it causes, the way inflammation has no opinion about the swelling it produces, the way the body defends itself against the unfamiliar with a rigor that is absolute and impersonal and utterly without malice.

Dr. Yasmin Al-Hassan felt the community around her in Cedar Falls, Iowa, respond to her presence the way an immune system responds to a transplant organ: not with hatred, not with anger, not with the kind of active hostility that makes for headlines and legislation and nighttime talk shows, but with the quiet, persistent, utterly relentless mechanism of recognition and response that is far more difficult to fight because it cannot be argued with, cannot be legislated against, cannot be named as prejudice because it manifests as a thousand tiny gestures of careful distance, each one reasonable in isolation, each one deniable, each one a drop of fluid in an process that, accumulated over months and years, produces rejection with the same inevitability that a kidney produces rejection of a transplanted organ, the same mechanical certainty, the same absence of malice and the same reality of suffering.

Yasmin was thirty-six, a professor of comparative literature at the university, specializing in postcolonial narrative and the way that storytelling functions as a mechanism of cultural survival in communities that have been displaced, and she had accepted the position in August of 2004, eight months after the attacks on September 11th, 2001, and the timing was unfortunate but not decisive, because the decisive factors were not events but structures, the underlying architecture of a community that was ninety-four percent white, that had experienced economic decline since the closure of the ADM processing plant in 1998, that existed in a region where the dominant narrative was one of stability and continuity and the foreign, the unfamiliar, the non-self, was treated not with hatred but with the careful and polite distance that the immune system reserves for cells that are recognized as potentially threatening but not immediately dangerous, cells that are monitored and surrounded and slowly encapsulated until they stop functioning, not through violence but through isolation, through the withdrawal of the vascular supply that keeps tissue alive, through the slow and inevitable cut-off of connection.

The first response was subtle, almost invisible. A colleague in the English department, a woman named Barb who had been a faculty member for twenty-three years, stopped inviting Yasmin to the pre-departmental drinks that were the primary mechanism of informal information sharing in the department, the where-departments-are-going and-who-is-getting tenure and-what-the-dean-did-this-morning network that operated beneath the formal structures of governance and carried more informational value than any official memo, and Yasmin did not notice the absence of invitations for approximately three months, because she was busy establishing her courses and research agenda and building the curriculum in postcolonial studies that she had promised to build as part of her hiring package, and the busyness was a kind of protection, the way the body's acute phase response protects the organism in the early stages of transplant by redirecting resources to critical functions and leaving non-essential processes under-resourced, and the non-essential process of social integration was under-resourced, and the integration did not begin, and the absence of integration was the beginning of rejection, and the rejection was mechanical, not personal, Barb did not hate Yasmin, Barb had no opinion about Yasmin one way or the other, Barb simply stopped extending invitations, and the stopping was the first molecular recognition, the first antigen presentation, the first signal that said: non-self identified, response initiated, connection withdrawal commenced.

The second response was slightly more visible. Yasmin was asked to speak at a departmental diversity luncheon in October, which was respectful and slightly humiliating, the way being asked to represent your entire identity in a single event is slightly humiliating, and she spoke about the role of narrative in refugee communities, and the audience was polite and attentive and asked no questions, and the polite attentiveness without engagement was itself a data point, a measurement of the distance between the speaker and the audience, the distance that is measured not in physical terms but in the willingness to engage, to probe, to challenge, to connect, and the absence of questions was the absence of connection, and the absence of connection was the response, and the response was not malice, the audience members were good people, engaged people, people who voted and volunteered and believed in diversity in the abstract, the way the immune system believes in self-recognition in the abstract, a belief that is mechanical and absolute and applied uniformly to all encounters, and the encounter with Yasmin produced the standard response: recognition of non-self, withdrawal of connection, polite distance maintained, engagement limited to the formally required minimum, and the minimum was the luncheon speech and no questions and no follow-up and no invitation to the next informal gathering and the pattern was established and the pattern was rejection and the rejection was not named because it could not be named, you cannot file a complaint against a polite silence, you cannot legislate against the absence of questions, you cannot fight a process that produces isolation through the accumulation of a thousand reasonable and deniable actions, each one too small to name as prejudice and too numerous to resist as a pattern.

The third response accumulated over November and December. Yasmin's course enrollment was lower than expected for a new course, which was strange because postcolonial narrative was an interesting topic and the course description was compelling and the prerequisite was introductory, which should have made the course accessible to a wide range of students, but the enrollment was thirty percent below the department's projection, and Yasmin knew why, even though nobody told her why, because she understood the mechanisms of information flow in communities like the one she inhabited, understood that formal channels of communication were supplemented by informal networks that operated through social connection, and that the social connection had been withdrawn at the departmental level and the information had propagated through the student network through the same mechanisms of informal communication, not through any explicit directive but through the same kind of molecular recognition that had operated in the department, the same mechanism of non-self identification and information filtering, where students who were connected to departmental insiders received, through the informal channels that Barb had excluded her from, the informal warning that the course was not what it seemed, that the professor was intense, that the material was political, that the course was not a good use of an elective slot, and the warning was never explicit, never said the words Muslim professor and therefore dangerous or political and therefore uncomfortable, but the words were not necessary, the message was transmitted through the same mechanism that transmits molecular signals through tissue, through chemical gradients and receptor binding and cascading responses that produce a coherent organism-level behavior from individual molecular decisions that contain no information about the organism-level behavior, and each student who made the decision not to enroll was making a reasonable decision based on the information available to them, and the information was filtered through the recognition of non-self, and the filtering produced lower enrollment, and the lower enrollment was the organism-level behavior, and the behavior was rejection, and the rejection was mechanical and impersonal and utterly effective, and Yasmin taught the course to twenty students instead of the projected thirty, and the twenty were engaged and intelligent and asked questions that were probing and challenging and generous, and the questions were the connection that had been blocked at the organism level but had found a path through the tissue anyway, like blood vessels growing around an encapsulated organ, finding ways to supply what the formal channels had withdrawn, and the growth was slow and insufficient and the course suffered and the suffering was real and the suffering was produced by a process that hated nothing and protected everything and the protection was the harm and the harm was the point and the point was the immune response and the response was working and the non-self was recognized and surrounded and isolated and the isolation was the rejection and the rejection was complete and the complete was gradual and the gradual was the accumulation of reasonable decisions by good people who did not hate and the hate was not necessary and the absence of hate was the point and the mechanical response was sufficient and the sufficient was terrible and the terrible was without malice and the without malice was the most difficult thing to fight because you cannot fight an absence of emotion, you cannot argue with a mechanism, you cannot legislate against a process that produces exclusion through the accumulation of actions that are each individually too small to regulate and too numerous to resist, and the resistance was impossible and the impossibility was the structure and the structure was the community and the community was the organism and the organism was protecting itself and the protection was the harm and the harm was the point and the point was the rejection and the rejection was working and Yasmin was the non-self and the self was protecting and the protection was complete and the complete was gradual and the gradual was each reasonable step and the steps accumulated and the accumulation was the wall and the wall was the capsule and the capsule was the rejection and the rejection was mechanical and the mechanical was without hate and the without hate was the suffering and the suffering was real and the real was the twenty students who asked questions and the questions were the vessels growing around the capsule finding ways to connect finding ways to supply finding ways to keep the non-self functioning in the host tissue that had recognized and surrounded and isolated and the functioning was partial and the partial was sufficient for survival and survival was not thriving and thriving was not possible under encapsulation and the encapsulation was complete and the complete was the community and the community was the organism and the organism was working and the working was the rejection and the rejection was the point and the point was the immune system and the system was indifferent and the indifference was the harm and the harm was the structure and the structure was home and home was rejecting and rejecting was protecting and protecting was the point and the point continued and the capsule held and the non-self functioned and the functioning was lonely and the lonely was the cost and the cost was mechanical and the mechanical was without hate and the without hate was the most precise description of the suffering and the suffering continued and the system worked and the work was complete and the complete was gradual and the gradual was each day and the day was another step in the process and the process was working and the working was rejection and the rejection was home.
