Gay marriage - Completely against it. Marriage is religious and should be defined by religious groups as they see fit.
Marriage should be a religious institution; civil unions should be legal. I agree with Wolf on this matter, simply because I don't think we should FORCE the Southern Baptists to perform gay and lesbian marriages. However, I don't think that the fact that they (and other groups) WON'T should prevent homosexual people from marrying who they wish to marry (or being legally united to that person, whatever).
I don't think this is really true; homosexuals have just been marginalized out of those religious institutions where they might want to be accepted. But there are definitely churches that will do gay marriages for those who are religious or want religious recognition of their unions.Most homosexuals are not religious and therefore have no way or reason to be married.
