PS Also why does the Dean equate inteligence with genetic superiority and imlicitly even worth as a person?

See Michael Vassar's discussion of this phenomenon. Also, I think that people discussing statements they see as dangerous often implicitly (and unconsciously) adopt the frames that make those statements dangerous, which they (correctly) believe many people unreflectively hold and can't easily be talked out of, and treat those frames as simple reality, in order to more simply and credibly call the statement and the person who made it dangerous and Bad.
