I don't care. Some of my friends are against this for religious reasons and I even got into an argument about it not that long ago on religious grounds. I tend to always come back to "It isn't our job to judge", which is how I genuinely feel and is what I additionally will fall back to when I either don't care enough to be bothered or feel conflicted, while the other side of a disagreement here sites scripture saying that homosexuality is wrong and in the recent argument it was put to me "You don't actually think we're built to have sex with one another like that?" I said no, but looking back on it, there's a lot of ways that we don't need to have sex with one another but it doesn't make it wrong or mean that it isn't going to feel right.
Fortunately, its not my battle to fight, however as far as legislation goes, I do idealise that the government stays out of religion unless they're protecting people's rights and that means that even if I were to be wrong, and were to wake up tomorrow and say "Its not a judge ye not thing," for whatever reason, I'd still feel that people should be free to make their own mistakes... which happened to be the way I looked at abortion for a while until I came to point of even less understanding (more confusion) and decided that I can still be content even while not having the answers.
As for being gay goes, and a lot of other things, I started life as an Athiest, became a Christian, struggled for an eye to eye understanding with some dogma, thrown out some radical dogma, became content that the bible is indeed a man made book, inevitably, and that even if its divinely inspired its had our dirty hands all over it since the beginning, and now I find myself more of one of those "pick and choose" Christians but not from the perspective of "I don't believe this and I believe that," but more like "I don't know, don't have the answers and never will," and I think this is the more important (for me, right now) of a spiritual message than all the ins and outs and dos and donts that comes with strict obedience. Some people see strict obedience as being the route to eventually loving one another, and they may be right. I see strict obedience, without understanding, as the route to isolating people including myself.
And that... is way more than what I think about Gay Marriage.
In all honesty, sometimes I think the Buddhists have it right, but they have some pretty out there foundations that their direction stands on. Sort of odd that Atheists don't have more a look at Taoism through a Lao Tzu perspective, now that I think of it. ...Then I come back to what I already know and say "Yeah that seems right."
For. Government and religion shouldn't be related at all. For legal reasons marriage should be irregardless of gay/straight. Marriage in a church is different. But gay people should get a legal document of marriage.
