[Serious] Please convince me gender is binary

[Anomalocaris]

Yes, that insidious "stereotyping" of the sexuality of an animal by which sexual organ it has.

If some societies determine reproductive identity by reproductive capacity, then that's sensible enough.  They are, after all, the reproductive organ of the species.  Certainly, if I was single and dating a female with an expectation of marriage, I would assume she was capable and willing to reproduce with me unless she specified otherwise.  If she weren't, I wouldn't hate her, but if I wanted to have children, I would have to look for a different partner.

Now, treating someone badly because they cannot or will not reproduce is another issue.  Making people feel "less than" is a violation of the social contract, and is a dick move.  That being said, if the only way to make someone feel complete is to play pretend, then I don't think anyone has the right to ask the people around them to do that.

Anomalocaris, I get the sense that you may be trans or otherwise non-binary-gendered.  It's personal, but if it is so, I'd like to talk about how you would want me to treat you, and I'd like to tell you how I would treat you, and we can see how much consensus or disagreement we might have.

You get the wrong sense.   I am unitary gendered.  However i think a person’s gender in practice need not be unitary and can consist of facets associated with different stereotypical genders.   Take you for example, I sense you may be binary gendered, so you seek to deny or disguise that socially regrettably awkward fact by asserting vehemently and ostentatious that each gender must be unitary.
