You know, I don't think that the only reason gay people get married is to hold with tradition. I think that's maybe a reason for some, but more importantly I think there are a lot of gay people who are religious. A gay church in Dallas, Texas, Cathedral of Hope, paid for my college tuition, and I live in Alaska! They have enough partitioners donating money that they could afford to do that. The Metropolitan Community Church, which caters to the GLBT population, is really growing, and there are so many denominations of traditional Christianity that are now accepting us more and more, such as the Episcopalians, ELCA Lutherans, some Protestant churches, etc.
I just think it's messed up that the UK won't give it's GLBT citizens equal marriage. WTF is with that? At least it's better than in the US.
