" Every immunoreaction is a reaction to Otherness. Now, however, Otherness is being replaced with difference, which does not entail immunoreaction. Postimmunological—indeed, postmodern—difference does not make anyone sick. In terms of immunology, it represents the Same.2 Such difference lacks the sting of foreignness, as it were, which would provoke a strong immunoreaction. Foreignness itself is being deactivated into a formula of consumption. The alien is giving way to the exotic. The tourist travels through it. The tourist—that is, the consumer—is no longer an immunological subject. "
