Saying what two people do in their own bed room is none of our business is not paying attention to the entire issue. I have no problem with gay relationships and what goes along with them.
As you should know, marriage is not just about sex.
It means many times paying less taxes, being covered by your partner's insurance from their job, etc.
Gay marriage is not an issue between the man and man or woman or woman (or whatever). It effects everyone's pocket book. If it happens, we all will end up with higher insurance premiums and higher taxes (fair to assume that since less tax money and insurance would be collected on account of more married people).
On the other hand, lawyers would enjoy being able to make their pay days off of gay divorces
