Eh, I don't know how the Powers-That-Be regard same-sex marriage, so I'm going to leave Them out of the equation.
That being said:
If churches/religious groups don't want to perform same-sex marriages, that's cool. I think they have a right to abstain from performing rituals that clearly go against their faith/beliefs/whatever. Ye can't force a church to bestow a sacrament that they feel is undeserving.
However, I see no reason why two men or two women shouldn't be allowed to get "married" in a courthouse or town hall - after all, it's not (or at least shouldn't be) a religious institution, right? Ye olde separation of church and state.
Of course, there's the argument over who owns the word "marriage" and changing the definition thereof what whatnot...personally, I don't care what anyone calls it as long as the rights and recognitions are universal. I don't understand why there's so much haggling over vocabulary, but I'm not a lawmaker or politician so I guess bumping up the rights of civil unions is more complicated than I feel it should be...
Meh.
In the end, I guess I just think it's ridiculous that two gay people cannot get "married" and have that legal rights, protections, and inter-state government recognition as married hetero couples. Ah well...
On a side note - does anyone know where I can read an argument against gay marriage that doesn't involve some sort of tie to a spiritual/religious belief? Something completely secular? I've been searching for a while and have read a few but I'm always interested in reading more.
