Is it ever OK to question a political candidate's religious beliefs?
Of course it is. If Jim Jones (of the ill-fated People's Temple) were alive and running for office, could we challenge him on his religious beliefs? What about Sun Myung Moon? He considers himself to be a Christian and is very politically conservative. David Koresh? Marshall Applewhite? A Satanist? A Wiccan?
The only question is "Just how bizarre are Mitt Romney's religious beliefs?"
...Objecting to someone because of his religious beliefs is not the same thing as prejudice based on religious heritage, race, or gender.
. . ."I wouldn't vote for someone who truly believed in the founding whoppers of Mormonism... [which] is based on such transparent and recent fraud."
