One of my major theses is that there is no correlation between a high IQ and thinking like a rational human being. Sometime it is specifically those people who are considered really smart, who write and say the most INSANE things. Here is a quote from a well respected Jewish Israeli Professor [עפ"ל], author of numerous books, who gets paid a lot of money to share his thoughts:
In simple English: The Israelis=Nazis. The Arabs=Jewish victims of Aushwitz. To even argue would be an insult to both the Israelis, the victims of the Holocaust הי"ד and to our intelligence. My point is how twisted and distorted people's minds can be, despite their academic achievements.
I often note that many of the leaders of the Nazi party had PhD's. An education is no barrier to both stupidity and evil. [That doesn't mean that one shouldn't be educated. Just that it is no guarantee for any level of morality both in deed and in thought.]
