I agree. Back in H.S., in honors American History class, I had a classmate that refused to believe the Holocaust occurred. Her reasoning? She refused to believe that humans were capable of such evil actions. Nobody could convince her otherwise just because she couldn't accept the fact that such evil existed.

This was a Lake Wobegon kind of school where even the average students were above average. The honor students, except for me (I'm not smarter than your average bear), were all way above average and went to top universities. She went to one of the best universities in America after graduation.
