I fully agree with this and often make this argument, usually to 100+ downvotes on reddit and elsewhere. My only addition would be that there's probably as much deviation within the genders as between them. But that doesn't make gender a meaningless thing. The frequency of those aspects is important too. Only, say, 10% of women are "butch" personality types but 90% of men are. So holding up a butch woman as an example and going "See, see gender is meaningless" is unconvincing.

I think eventually society will sober up and realize that when we talk about social aspects, more than likely we're talking about personal types. Certain ones simply exist with higher frequency per gender.

I feel like we're on this long path of migrating away from "default brain" assumptions made about race, nationality, gender, etc and will probably settle on something like the modern day understanding of personiality types. Its scary how well I fit the INTJ mold. The idea that I represent all men or am part of masculine culture is fairly ridiculous. Ladies, I find male ISTJ's and ESTJ's hard to deal with as well.
