In their push for government endorsement of same-sex unions, gay advocates insist they only want to extend the institution of marriage, not to change it in any meaningful way. At the same time, some of the leading married activists on this issue (like author and columnist Dan Savage) admit to participating in group sex with their spouses and rejecting heterosexual standards of monogamy. A New York Times Magazine profile of gay “married couples” revealed that nearly all of them practiced “open,” non-exclusive relationships. While man-woman couples often fall short of perfect fidelity, they rarely hold up sexual adventurism as a new ideal. Overwhelming majorities of Americans say cheating is wrong in all cases, so when prominent gay activists openly, proudly stray, they signal their unmistakable intention to redefine marital norms in a radical way.
