Honestly, the GOP’s anti science is what makes it so hard to understand for me. It’s not simply disagreeing with Darwinian theory, it’s demonizing Darwin and comparing his theories to the Nazis like Ben Stein did. The fundamentalist Christians that the GOP plays to for support sincerely do believe that to accept Darwin is to accept Satan. I’ve long had my disagreements with the Roman Catholic Church but at least they realize Darwin is legitimate science.
