It's misogynistic, because the ghost writer of Surely You're Joking Mr. Feyman!, Ralph Leighton, ultimately put into print narratives that encouraged men to see "ordinary" women as "worthless bitches". In the character of "Feynman": Well, someone only has to give me the principle, and I get the idea. All during the next day I built up my psychology differently: I adopted the attitude that those bar girls are all bitches, that they aren't worth anything, and all they're in there for is to get you to buy them a drink, and they're not going to give you a goddamn thing; I'm not going to be a gentleman to such worthless bitches, and so on. I learned it till it was automatic. ... On the way to the bar I was working up nerve to try the master's lesson on an ordinary girl. After all, you don't feel so bad disrespecting a bar girl who's trying to get you to buy her drinks but a nice, ordinary, Southern girl? We went into the bar, and before I sat down, I said, "Listen, before I buy you a drink, I want to know one thing: Will you sleep with me tonight?" "Yes." So it worked even with an ordinary girl! The story about direct consensual sex with one "ordinary girl" doesn't validate that men should have misogynist attitudes towards ordinary women. It's just confirmation bias. It matters, because training your mind to be misogynist until it's automatic would spill over into other aspects of your life, like how you treat female coworkers.
