You can be accepting of others, however facts are facts. Gravity doesn’t stop existing, because you don’t “behave” as though it does.

Gender is behavior, and it’s negotiable.

The OP is now deleted, however it states there is XX and XY chromosome. How is this behavior? How is this negotiable?

Legit curious.

The implication being based on those chromosomes, there is one way to behave; you must race with those of like-chromosomes. I think that's entirely up for debate, and for good reason. Further, there may be entirely new ways to organize our culture and society for broader justice for the marginalized. Organizing such things by gender breaks down (if justice is your lens) just like it does with race.

Your own statement reveals your bias. I never described a behavior or expectation, but and embedded genetically-shaped characteristic. Your accusation of me being "bigoted" is a stereotypical "extreme leftist" / "woke" accusation based on no fact.
