The fact that FIDE still enforces women's chess is a glaring example.
There is no man's chess, you know? Women can and do participate in open tournaments against men.
Woman's chess is a DEI program to incentivize woman's participation in chess in a more inclusive environment, because, surprise surprise, chess has a misogyny problem. You can argue that this doesn't work or something, but it definitely isn't there to protect men's egos (especially considering titles acquired in women's chess tournaments are worth less than regular titles).
