Two words:
Hot lesbians.
One concept:
Gay divorce court on TV. Who wouldn't watch that? Oh My!
But to be serious for a second. It really is not that big a deal to me. The less the government involves itself in my life or the lives of those around me the better. If two guys or two girls want to live there lives out with each other and have a civil union to show that they are together thick and thin, or if a church wants to perform a marriage for them, I really do not care. It is no more my concern then my marring a women is to them. Or entering into a civil union with one.
