Sex and the Gender Binary

i heard so many people making the argument that sex is binary, and using science as a reason for discrimination. No, actually, scientifically, that's wrong, and sex isn't binary. The only way to really understand someone's gender identity has nothing to do with all this chromozomes or any sort of genitalia we've talked about in the past. Treating people with respect and dignity and validating their existence is what matters at the end of the day. Go high school teacher tell your students there aren't two sexes; they were just told by an English teacher who didn't know better.
