Marriage is one of those institutions -- along with religion and military service -- that restricts freedom. Marriage is about making a commitment that binds you for decades to come. It narrows your options on how you will spend your time, money and attention.

Whether they understood it or not, the gays and lesbians represented at the court committed themselves to a certain agenda. They committed themselves to an institution that involves surrendering autonomy. They committed themselves to the idea that these self-restrictions should be reinforced by the state. They committed themselves to the idea that lifestyle choices are not just private affairs but work better when they are embedded in law.

And far from being baffled by this attempt to use state power to restrict individual choice, most Americans seem to be applauding it. Once, gay culture was erroneously associated with bathhouses and nightclubs. Now, the gay and lesbian rights movement is associated with marriage and military service. Once the movement was associated with self-sacrifice, it was bound to become popular.

Americans may no longer have a vocabulary to explain why freedom should sometimes be constricted, but they like it when they see people trying to do it. Once Americans acknowledged gay people exist, then, of course, they wanted them enmeshed in webs of obligation.
