Trigger words: Gender gender (8) genders
Indicator sentences: Gender is a physical thing.
Negotiation parts: People tend to say things like sex is what is in your pants, and gender is what's in your head. Or that gender is just a social construct (it turns out that sex is also a social construct, but it's a bit complicated, and not part of this post).
Trigger words: androgyny
Indicator sentences: Androgyny is based on appearance, and not identity.
Trigger words: Sex
Indicator sentences: It's not the act of sex we're talking about. We're talking about the existence of sexes. Aka penis and vagina.
Negotiation parts: I know. I was just trying to be funny, because what you wrote invites the transitive property. You wrote: If sex is a social construct, then social construct is meaningless. Then by the transitive property, you think sex is meaningless. Now even if you meant penises and vaginas, you still didn't say why you think they're meaningless.
