reaching by calling it 'multidimensional' when the entire article is two dimensional classifications. that's how. the headline is shit.
placement of your gonads or breasts has nothing to do with how male or female you are. what are you talking about? some men develop breasts due to cancer, doesn't change them to become women, they are just men whose breasts developed due to hormonal triggers that are not normally present.
like, I understand the motivation to normalize intersex people by claiming everyone is intersex, but that's not a useful in any way, it's just trivializing things.
I'm more than open to have hormonal cutoffs for sex/gender definitions, but I also understand that is a total other bag of worms once you start doing things that way. It would a more properly scientific way to define male and female, but socially people would lose their fucking minds if that standard was applied to sports or other social controversial areas where sex definition is a sorting mechanism.
We already exclude people based on drug use for tons of things like jobs, sports, etc.
