None of those answer my question. The first simply asserts that non-binary is a thing and that through self identification surveys people have identified themselves as nuetral or the other gender in the past. There is no cited studies on gender-fluidity that I could see.
The language link is broken on my end
The anthropology simply states that there are male and female sexes that are cis and there are male and female sexes that are not. They identify them as a third or fourth gender because they have preferences and or personality types outside the norm. None of this addresses my question of how gender is different from personality.
A mix of all three if I'm being completely honest. I believe in personal freedoms for all, right up until they infringe on the rights of another person. I can't go into more detail without breaking forum rules.
I'm a believer that there are certain aspects of peoples personalities that are determined by genetics, and there are general patterns of behavior. Stereotypes exist for a reason and can be useful tools for dealing with people you do not personally know. Obviously this changes when you get to know a person, because few people are a walking stereotype.
Finally, and I probably should have lead with this. Your perception of reality and mine do not match up, so I wish to learn more about your perceptions so that I can figure out were we are the same and use that to further both of our understanding.
Given my perception of (probably earned) hostility from that poster, I really wasn't expecting a joke. It went over my head. Sorry.
