Seriously, I thought there was already an agreement on how to approach this. Sex is the biological identification. Gender is the social identification. Sexuality describes the relation towards other sexes and genders. Neither take is really is disagreeing with the other, but rather than refer to proper identification and the differences between gender, sex, and sexuality, all they are doing is raising drama and playing hot potato with the terms that already cover this.
Yes, sex had a biological objective determinant (except for outlying cases). Yes, gender is subjective to ideology. However someone wants to identify themselves should be defined by their gender, yet things like how they get treated at the hospital is going to be determined by their biological sex. “Experts” (usually the self-appointed kind) unwilling to make any compromise at the risk of putting their big massively throbbing authority at risk, more at eleven.
In other words, what’s left when a leopard eats the face off of another leopard.
