Before you vote for a Republican, just remember the Court system. The Texas Sodomy ruling could be overturned if a Republican President appoints more "strict constructionist" justices to the Supreme Court. Individual cases involving partner rights, adoption, etc, would not go well for gay and lesbian citizens with "conservative (read bigoted)" judges in federal courts and regional Appeals Courts.
I am not surprised about many people's feelings about Obama. I figured that people who focused so much disapproval on a woman candidate would not be jumping to vote for a Black man either. And, please don't try to tell me it's just Hillary Clinton. There is just as much misogyny, if not more, than racism in this society. The white, heterosexual male power structure will tolerate no threats, even if its only justification is "that is the way we have always done things."
