Christopher Hitchens, my favorite conservative athiest, has written a crackerjack editorial about Romney's duck, cover, obfuscate and dodge strategy with regard to his religion and answering questions about it in the press. My position: While I hold no personal animosty toward individual Mormons per se (with the lone exception being Orson Scott Card), the church as a whole has the kind of nutty supernatural/science fiction nonsense shared by Scientology. Purported golden plates and faux old testiment nomenclature are not enough to make me a believer. As I have said before and am proud to say again, I believe Joseph Smith was a False Prophet. If I didn't, I would be a Mormon, wouldn't I? I suppose that goes without saying, and that by saying it, I'm effectively spitting in the eye of the CJCLDS--be that as it may. The famous anti-Morman South Park episode, which turns the tables at the end, taught us: all religions are a little bit nutty--what the church believes doesn't matter, it's what the flock does that matters.
Hitch raises the specters of racism and polygamy that the LDS eschewed by prophetic fiat at critically convenient times. Some might see that as divine inspiration, while others might see it as the Prophet holding his spit-covered finger in the wind.
My position: I don't know what's in Romney's heart, nor do I presume to judge. I only know what he does, and says. Right now, he's saying nothing about an issue that matters.
