George Weigel argues on National Review Online that the passage of gay marriage in New York “is an exercise of power that libertarians ought, in theory, to resist, not support.” Here is more:
Marriage, as both religious and secular thinkers have acknowledged for millennia, is a social institution that is older than the state and that precedes the state. The task of a just state is to recognize and support this older, prior social institution; it is not to attempt its redefinition. To do the latter involves indulging the totalitarian temptation that lurks within all modern states: the temptation to remanufacture reality. The American civil-rights movement was a call to recognize moral reality; the call for gay marriage is a call to reinvent reality to fit an agenda of personal willfulness. The gay-marriage movement is thus not the heir of the civil-rights movement; it is the heir of Bull Connor and others who tried to impose their false idea of moral reality on others by coercive state power.
