It also doesn't me we can't.
Sure, but we should have a reason for doing so.
Your problem, and it may be because you've never left the house, is that you're trying to deal in absolutes.
It's my opinion. It should be absolute. Things are open to interpretation. Judges have bias. I know. But I'm not arguing that no judge will ever disagree with me or that he won't let his beliefs influence his decision in a way that he shouldn't. In my opinion there is no valid legal reason to deny same sex couples the right to marry. You say you don't care if they marry. Great. If you think they shouldn't marry, that's ok too, here is where you can say why.
