Now I understand why my first post was not detected as a satire of the anti-same-sex marriage crowd. There are people in this forum stupid enough to have written something like that in sincerity.
It isn't bigotry to accuse someone of being a bigot, and it isn't bigotry to treat them accordingly. It's the worst kind of relativism to suggest that the entirely appropriate disapproval of the arbitrary exercise of power over a whole demographic is the moral equivalent of that arbitrary exercise of power. Refusing to allow same-sex marriage must have an extreme rational justification, and no rational justification has ever been given. Anyone who persists in the view that we have the right to deprive same-sex couples from one of their rights despite that lack of rational justification can only be a bigot.
