If they are, it's a separate argument, and more - it's a separate argument in each religion.

I've heard some campaign commercials that advocate anti-gay-marriage laws and ammendments by implying that priests will be forced to officiate over gay marriages. The fact is, even if every other religion, and every nation on Earth, allows gay marriage, the lone holdout would still be perfectly free to refuse.

Interfaith marriage happens all the time, even though there are plenty of religions that won't officiate over them.

That's your choice you can go to a JP. ;)

The problem with polygamy is that people would use it for business purposes.

Our marriage had nothing religious at all in it... so, in the eyes of a neo-con are we married? Not that I give a shit, but religion and marriage should have nothing to do with each other. The state and religion should have nothing to do with each other, EVER.

I don't think that's a problem for anybody except the people who try to do it. There are a ton more legal implications to marriage than the ones that might be attractive from a business standpoint, and that could get real creepy real fast.

But if someone manages to make it work, more power to 'em.
