I don't think there's anything especially abnormal about being bigoted, stupid, uneducated, or evil, and that remains true whether we are talking about Republicans, Democrats, or any other group of people.
The other key thing is that the definitions of these terms vary greatly. No one with a high school degree would have been considered "uneducated" in 1900, and given our modern definition of "bigoted," virtually every American adult in 1950 would be considered a bigot. When someone calls their opponents evil, bigoted, etc. it testifies to the moral framework that said person uses, which in turn leads them to formulate benchmarks or definitions for what constitutes evil, bigoted, etc. The same thing applies with "normal" as well, of course.
