Don't accept the framework at all. Gender doesn't apply to people. It is a purely linguistic construct that determines the usage of word-forms in a gendered language.

Humans are a sexually dimorphic species with plainly observable physical, mental, and behavioral differences between the sexes.

The exceptions don't negate the existence of the general (normal) case.

Because everything about "gender" is fake the only way the retarded proponents can pretend it exists is to use logical fallacies, social pressure, and obfuscation against anyone who questions them. Their goal isn't to prove themselves right. Their goal is to isolate, discredit, wear down, and chase away of anyone who isn't in ideological lockstep with them.
