Hi Peace, I now fully understand why you wouldnt want to discuss Hitler, and anyone who doesnt isnt worth your time.
As for Clifford Olsen and Charles Manson, they are worth learning about, i know that Ted Bundy is a serious point of discussion when studying to become a phyciatrist. I dont know where you come from, But In london there were a couple of Brothers called the Kray twins, they were evil beyond comprehension, but they took in the public. now they almost have cult status, If they had been politicians who knows what would have happened.i know places in East london where you wouldnt dare say anything about them, you would be lynched. But they are interesting to read about and learn about. Knowledge is power. you can get a balanced view if you try to see it from the other persons side.
