Third genders are/were just a way to ostracize trans women and trans men and turn us into second-class citizens.The queer theory theyfabs and the people that romanticize third world cultures before the evil white colonialists came tend to misunderstand what third genders are/were. It's not a good thing. It doesn't make you or me "valid."
Nonbinary as we know it is a white, anglo culture invention and you all have to deal with that fact.
