As for true public opinion goes, I think the overwhelming majority of people most likely fall in to the "what other people choose to do with their lives is their business" field of thought. That is the attitude of almost everyone I know, including myself. If a gay couple wants to get married, their ability to do so in no way diminishes my relationship with my wife, or my day to day life in anyway at all, really. Let 'em have at it. All this political posturing and stupid law making is just that. Stupid. If the federal government makes a decision on this, the states aren't going to be able to do much about it, anyway.
Live and let live, I say.
