Andrew Sullivan on marriage equality

The premise used to be that homosexuality was an activity, that gays were people who chose to behave badly; or, if they weren’t choosing to behave badly, were nonetheless suffering from a form of sickness or, in the words of the Vatican, an “objective disorder.” And so the question of whether to permit the acts and activities of such disordered individuals was a legitimate area of legislation and regulation.

But when gays are seen as the same as straights—as individuals; as normal, well-adjusted, human individuals—the argument changes altogether. The question becomes a matter of how we treat a minority with an involuntary, defining characteristic along the lines of gender or race. And when a generation came of age that did not merely grasp this intellectually, but knew it from their own lives and friends and family members, then the logic for full equality became irresistible.
