Hitler was a drug adicted lunnatic with a power trip why would anyone say he was anything different.
Hitler's beliefs sure are no selling point.
Dawkins is making the mistake of not separating Hitler the person from his broad array of likes and interests. Hitler was also interested in art. (He plundered priceless art from museums and private collections all over Europe.) Does that make art bad, too, just because Hitler happened to appreciate good art? Dawkins is being dumb. He should have stuck to hosting TV game shows.
