I mean, hell, sure, lets say for the sake of argument, "women belong in the kitchen, pregnant, and barefoot" (the single most classically sexist thing I can think of at 6:30 in the morning), women raise our children, both boys and girls: if you truly believe this, why didn't you marry a woman with multiple PhDs and a high IQ, so a much more intelligent forward-thinking educated woman is raising your children, thus giving them a better chance in life and thus spreading your genetic legacy more favorably (the driving force behind 99% of human culture and society)?
Seriously, sexism just doesn't logically make sense. If you're sexist, and a CEO or a major investor, please drop out of the game and let someone more efficient than you take your place.
Edit: I don't care if you downvote me, sexism is still wrong and needs to be called out as much as possible so we can exile people who are abusing their power to promote sexism.
