Sure, there's even a name for that kind of factors: sexism. That's the reason pay gap is a problem that is talked about but life expectancy gap isn't.

Feminism was supposed to fix sexism not to reinforce it, though.

Well, yes, in the end it's just art critique. But even that should be a topic that you can discuss without being labeled as chauvinist the moment you disagree.
