In case you haven't heard that Prop 8 was overturned by a federal judge two days ago, you're welcome. Facebook and the rest of the interwebs have, of course, exploded, which is great because it's been a while since I got a good dose of internet venom. Personally, I think it's much ado about nothing until the appeals climb all the way to the Supreme Court.
When Prop 8 was passed almost two years ago, it seemed clear to me that it had no real basis aside from private religious views. Maybe it's my relatively small sample size of friends, but it seems like that is still the case. Judge Vaughn Walker said this explicitly in his decision, and the Prop 8 defense lawyers apparently couldn't make a very good argument otherwise.
I almost hate to say this, because I want to think the best of people and I know there are some people who have been convinced to support Prop 8 on grounds other than religion. But for the great majority of Prop 8 supporters in my experience, it simply boils down to the idea that God, the Bible, or church leaders said so. Deep down at a bedrock level, that is the fundamental reason to support Prop 8. It really, really is.
Of course, no one ever leads by saying they object to gay marriage because of their religion. We all pay lip service to the idea that our laws need to serve some secular purpose. But I've seen too many people trot out arguments like "homosexuals can't procreate" or "homosexuals are inadequate parents" or "churches will be forced to perform gay marriages" or "marriage has always been between a man and a woman." And when each of these arguments is refuted, it usually comes down to, "Well, I believe God said it's wrong."
But private religious views cannot be the basis of law in the United States. I wish more people would realize that the separation of church and state is as much a protection for your religion as anyone else's. Just because your religious view happens to be a majority does not make it constitutional to pass discriminatory laws based on your religion. If the rise of Islam overtakes Christianity in the next century, will you fight to pass laws criminalizing graphic depiction of Muhammad? If you understand why not, you should understand that Prop 8 has been rightly struck down for the exact same reason.
