The truthful (though not transparent) answer to this one is that I have avoided discussing this subject both in public (blogland) and private (family) because it is highly divisive. There’s a few things I don’t generally discuss. Gay marriage isn’t the only subject I stay mum on. Abortion is another one. So is illegal immigration. And organized religion. And vegans. (Just kidding, I talk smack on vegans pretty regularly.)
I’ve never heard or been involved in a conversation about these kinds of subjects where the people involved changed their minds. Usually it’s just an opportunity to fight, if not overtly, then disguised as “I just want to know where you’re coming from!” But, for me, most divisive subjects are not about a lack of information but rather a difference of opinion about where primary value lies.
I vote for, write letters about, and make donations toward causes I support. I just don’t talk about some of them.
That’s the truth, and I’m stickin’ to it.
