It's not really bigoted, but the evolution fight is used as a standard in the culture war. I have six friends from the same family that were all taught creationism and they still have better critical thinking skills than the average kid with a public education ends up with.

to be clear I think creationism is stupid and insupportable, but it didn't end up hurting them that bad and I know plenty of people with "better" educations that don't seem to be inoculated against believing stupid stuff. For instance, people I know that have expressed skepticism about vaccinations are evenly split between people I would classify as "conservative Christian" and "progressive".
