Gender studies is a very new thing, so I doubt you'd be hard pressed to find many who claimed it's been figured out. Though, I think what most gender researchers will agree on is there are more than two genders, and more variation in sex than a simplistic view of biology would make one think.
I struggle with the concept of gender because it appears to be akin to a ‘racialised theory of sex‘.
I’m male. My appearance, sense of dress, interests and attractions are my unique personality - I don’t think they come from a biologically inherent gender, nor do I think it’s socially progressive to promote the idea that they do or should.
Edit: Are you sure you didn’t downvote for ‘heretical opinion’ rather than actual content? Please explain, if not.
I think many gender studies point to how inherently difficult it is to separate biology, physiology and culture. And much of the issues come when those three things don't seem to line up. So much of the vitriol from all sides of the cultural debate seem to extend from, not necessarily the science of it, but how that should affect our policies and interactions with each other.
“Culture isn’t determined biologically (that’s a racist belief), nor does biology determine someone’s gender (and that’s a sexist one) - and any specific culture shouldn’t require individuals to conform to gendered roles in its service (that’s a human rights violation regarding basic individual freedom)” would be my response.
Sure, these things are hard to separate - the mistake is to think that means they’re mutually determined.
