Ehhh, I get the point, and I know it's exaggerated for the lolz, which it definitely got.
That being said, the fact that gender as a part of language is indeed a construct, the fact that humans have a strong history of making those constructs and organizing around them points to the underlying essence of what gender actually represents does have more of a non ideated origin.
And, generally, for the species as a whole, the binary works for both the body and the mind. The fact that there are a large number of people that don't fall close enough to the ends of the spectrum for it to actually be binary doesn't get rid of the fact that the percentage of people that don't fit the gender norms that are commonly associated with a given "sex" is damn low ratio.
That's why it's vital to protect that minority, mind you. That's why we have to take care of our own, and our own is every human being. I'm just saying that the issues around gender and sex are issues that stem from a pretty small minority. For the rest of the population, gender and sex aren't separate for the individual person.
I was just seeing the access ramp to the municipality office yesterday and it looked so steep and I just wonder how the hell are you supposed to go up lol
