Gentlemen prefer blondes.
Tens of millions of women subscribe wholeheartedly to these truisms. As we all know, the only reason so many women want to be blonde is because they've been culturally conditioned to follow Anglo-Saxon standards of beauty. Since the industrial revolution happened first in Protestant Europe, a northern white male power structure runs society. They've brainwashed everybody into believing in their superiority. If true, this conventional wisdom should also apply to men.
