Article examines intimate discrimination, focusing on race, sex, and disability, and identifies key norms for each category. For race, the norm is homogamy, or pairing with one’s own type; for sex, by contrast, the norm is heterogamy, pairing outside one’s type; and for disability, the norm is desexualization, rather than pairing with one group or another. The Article does not assume that intimate discrimination is necessarily bad. On the contrary, examining the nuanced landscape of discrimination in this realm is one of the Article’s main purposes. at the level of individual interaction, intimate differentiation based on these identity traits can be good, bad, or neutral, depending on context. For this and other reasons, legal regulation targeting individual differentiation on these bases would be woefully misguided.
