Good points, and I think we generally agree. I definitely didn’t mean to exclude anyone in those real or hypothetical situations you mentioned. To me, those examples are more about showing how gender is, or can be, biologically fluid. There are many “odd” situations that aren’t binary. So amongst the many unusual ways that sex can occur biologically, “male brain in a female body” or “I reject the concept of gender entirely” are valid and believable.

I agree with your last point as well, but in the context of this post, would you tell Rachel Dolezal that she says she’s Black, so she’s Black? I guess I was trying to find some sort of difference between gender and race identity, the way the question was posed.

I’m definitely not claiming to have an unassailable argument, so thanks for responding with good points.
