 Recall that some arguments for same-sex marriage claim that central, exclusive relationships are valuable, and that same-sex marriage would benefit gays and lesbians by encouraging them to enter such relationships (e.g. Macedo 2005; see 3.3). But critics of heteronormativity, drawing on gay and lesbian experience, have argued that the central, exclusive relationship ideal is a heterosexual paradigm. Such critics note that gays and lesbians often choose relationships which are less possessive and more flexible than monogamous marriage. Instead of recognizing the diverse relationships found in the gay and lesbian community, same-sex marriage would assimilate lesbian and gay relationships into the heterosexual model. While some advocates of same-sex marriage argue that marital status would confer legitimacy on same-sex relationships, these critics argue that the state should not confer legitimacy (and hence, implicitly, illegitimacy) on consensual adult relationships, any more than it should so discriminate between children born in or out of wedlock. Such conferrals of legitimacy are thought to discourage diversity. Moreover, same-sex marriage would expose gays and lesbians to the disadvantages, even evils, of marriage: economic incentives to stay in loveless marriages and reduced exit options which facilitate abuse and violence (Card 1996, 2007, Ettelbrick 1989).
