Sarah Palin, in 2008, blamed man for climate change.
She later changed her position, but surely that doesn't mean she wasn't a Christian in 2008 or 2007 or 2006.
It just means she was misinformed, and possibly ignorant, and of course, a brainwashed devotee of Al Gore. That's all.
I'm a little shocked Rush would attack religious people like that. To exclude someone from your religion based upon their view of an evolving political/scientific issue is madness. Although I guess there were people calling Copernicus a heretic and the devil because of his theories too. It's just ignorance.
