@old europe,
oe, of course you won't accept this, but Ray is apparently a scholar in behavioral science, psychology, including social psychology. He also taught social psychology, and his particular interests have been psychological authoritarianism, conservatism, racism and achievement motivation, which have spawned over 250 publications.
Now, I happen to think that the issue of left vs right, or conservative vs liberal, is indeed as much a psychological study as it is anything else, and I also think political movements are rooted in social psychology, or put into different words, it is the study of the moods of cultures and societies. And also face it, Hitler was a psychological anomaly of history, and perhaps a figure that is best analyzed by a social psychologist rather than a historian without the psychological training or understanding of human behaviorial sciences.
So oe, how do you justify your opinions to be as good or better than John Ray's, when you have no credentials in the study of psychology or social psychology, or do you?
