Asking someone to give a sharp dividing line in a multi-dimensional bimodal but not discontinuous distribution is just nonsense.

In particular, being unable to give that strict difference (that does not exist) is not proof of not believing that the general bimodal groups exist, nor acknowledging that existence, nor saying that there is not general differences between the groups. It is not the gotcha that elementary school biology suggests it would be.

And you're essentially demonstrating my point. Your long, complicated, meaningless comment here - which boils down to sex being impossible to define - is now widely accepted, while someone like Scott Adams who would claim that chromosomes or sex organs are sufficient in defining one's sex, is perceived to be "off the rails". It's absurd.

I said exactly what I wanted to say, in as simple terms as I am capable. The fact that some people insist on reality being simpler than it is does not make it true.
