my point is: biological sex follows a bimodal distribution with some in-between data points that are not trivially assignable to one or the other pole, called "intersex" humans. they are a biological, medical reality, and they themselves ask to leave children alone and allow them to decide when and if at all they want medical interventions.

Even calling it bimodal obscures the truth, though. When people read "bimodal" they think of the two-humped-camel plot, when reality is like two 60-story skyscrapers a mile apart with an apartment building or two in between.
