First, I am a very conservative male heterosezual. That being said, I could really care less if two men want to be intimate. It has nothing to do with me so why should I care? As far as 'redefining marriage", words in the English language, any living language, is changed constantly. Two men saying they are married has no impact on my marriage, so again, why should I care?
As to moving south, I am planning that already. Not because of gay marriage but because of the foolish monetary policies of liberal states. I want to go somewhere I can keep the money I make and not support a bunch of lay-abouts. I wouldn't be surprised to fins a great many gay people giving up the possibility of marriage for the same economic stability.
