Good points--and ones I am receptive to as well. Gay marriage should be decided by the people, not judges. Gays need to make their case in the court of public opinion--they could sway opinion to their side (but really--when you see a couple of guys at the altar, that's just sick (confirmed homophobe))
I guess the answer is to not go to any homosexual weddings. I also feel that the people should decide, not the courts, but I can imagine that majorities in the blue states would be supportive of civil unions. What I would oppose is a Supreme Court opinion that legalized gay marriage throughout the land, but I think it's coming within five to ten years.
