as evidence, what it _means_ to be a man, woman, etc, differs from society to society. if you ask me to quantify this precisely, i will struggle. but it's plain for all to see.
The idea that gender is a social concept is so blindingly obvious that, like bbeonx I kind of assume that anyone making comments like yours about "common sense" is either blindly parroting talking points without thinking about them, or arguing in bad faith.
I think you're putting words into peoples mouths there.
Acknowledging that there is a social construct we generally know of as "gender" and acknowledging that certain stereotypes and common understandings of that concept exist is not at all the same thing as demanding that people should fit into the narrowest stereotypes that you can think of.
Also worth noting that you acknowledging the existence of sexist stereotyping is an acknowledgement of the existence of gender as a social construct.
An example of using the category normatively would be saying someone isn't American because they burn the flag. My experience is that most of the people using "gender" normatively don't differentiate it from sex.

the second post is actually about (a) me having understanding for a position of someone i disagree with harshly, and (b) the logical structure of an argument, not the underlying topic itself. it was in reference to the content of the link that was posted.
anyway, mods can take it down, i get why the rules are there. you're also right to ask folks to keep it clean. but i stand by it; dude just seems to have a trifecta of awful traits and i'm so so so tired of super rich tech dudes ruining the world.
