Actually, I've heard a secular argument:Agayek said:Honestly, I couldn't care less for gay marriage, but I've never heard an argument against it that was any stronger than "God said so!", and that's simply not a compelling reason. I'd like your take on it, since you clearly disagree.
Money. If we allow more people to get married, that means more people will get devorced, which takes up the courts time and money. And that also means that if they file together, they pay less in taxes. So we are left with a net loss.
Which means we either cut spending, raise taxes, or both.
The former is not popular with those on the left, and the second is not popular to the right.
Again, I don't necessarily agree with it. It just is fully non-God based.
