I know plenty of men who lived through that era (and one man who was born 4 years after Feynman) who are not in the slightest bit sexist. Or are at least far too polite to show it.

Feynman was clearly a bit of a prick. It also appears that he behaved rudely toward women [0]. In my opinion, the fact that there were some (significant) negative aspects of his personality doesn't take anything away from what he accomplished, or from the (significant) positive aspects of his personality.
