You assert that "prior to 1967, many states (maybe most of them?) required that persons who wished to marry be of the same race. The racism of the miscegenation laws is no longer 'respectable'."  You seem to think it follows that "the bigotry which heretofore prevented gay persons from exercising the civil right to marriage enjoyed by other citizens is now recognized, in law and by most people, as no more 'respectable' than the racism of the laws that prohibited interracial marriage."  That's a hoot.  Maybe you can spell out how simply being black, which is no basis for discrimination -- and prohibited by the 14th Amendment --- is like committing acts which have long been viewed as a crime against nature.   Maybe you can explain how the Loving v. Virginia case, which of course involved heterosexual marriage, said ANYTHING about the legitimacy of marriage between two homosexuals.
