I don't even see why there is necessarily an inherent assumption that social consevatism must be religiously derived.
For instance, my motivations for holding the socially conservative positions that I have, has absolutely nothing to do with anything remotely religious, as I am very secular and at one point was even atheist.
I didn't assume social conservatism must be religiously derived. I said that the secular policy arguments against gay marriage strike me as the least convincing of basically any policy arguments out there. I frankly can't imagine being opposed to gay marriage even as a social conservative, unless I was
ridiculously traditionalist-for-the-sake-of-traditionalism...and I think everyone here is more thoughtful than that. That's why I'm asking why the folks here are leaning what they are.
I also understand the tendency to turn against annoying things, but for a policy vote that has many years' worth of effects, voting on something so transient...
