What sucks is that I'm the sort of visual person that can say things like, "Gender is the way we exist in and move through a sexed culture" and like, I have a visual idea of what that means in my mind but how do I even convey something like that.
Gender isn't fake and sex is real, that's just not how any of this works. Gender emerges out of the way that groups of people sought to control reproduction, but that doesn't mean it starts and ends with reproduction, nor does it mean that it exists in the same manner for all people at all times.
