I've grown from being pro-gay marriage to be completely apathetic/conflicted.
May I ask why? I'm about to get married to my partner and would be curious to know what made you become less supportive of them, not as an 'idea' (because gay marriage is no longer in the realm of theoretical) but as actual event taking place between two people. What is it about gay marriages that puts you off them? Do you think that now that people have financial and next of kin rights that these are bad things and should be taken away from them?
I think Gavin Newsom put it best in that gaffe the Prop 8 guys jumped on. "IT'S GONNA HAPPEN, WHILE YOU WANT IT OR NOT."
Looking at the demographics of how people view gay marriage, I've come to the conclusion that legalized gay marriage is inevitable in the United States regardless of what happens. If someone comes up to me and says "yo we're going to have a referendum on it", I'd probably vote in favor. But otherwise, I don't think/care about it.
