Yes. I personally think this is great.

Even though I supported the other guy (who would have also done the same thing, as would any righteous SF politician), I think whay Newsom did was a step in the right direction. We need to take this to the courts, and see what kind of response it will get, cuz I bet they won't be able to find anything that would prohibit gay couples from marrying.
frankly, my own interest in this is simply because if gays marry legally, that undermines the "morality+religion should play a role in government" argument of the Christian Right. I'm obviously suspicious of any attempts to introduce religion into secular govt affairs (school prayer, 10 commandments monument, etc)
My own preference would be if we just created all civil unions, for gay and straight couples. Marriage is a religious institution, let the churches handle it. But if that's not the case, then just let gay people marry.
also, it's cool to break the law

. And its for a good cause. Unjust laws should always be fought.
