OMFG people should commit suicide.

Neapolitan strikes again with his rapier wit! :laughing:

I have some sense of what Ki is saying. I do not think think men and women "don't exist", but I would say that man and woman only exist as labels for classification schemes that the human mind uses to understand things (in order to make predictions and adjust behavior). They obviously have some consistency to them and are useful classification schemes, but most people aren't careful about recognizing the limitations of such classification schemes.

Men and women are biologically very different in general.

There's classically four different classifications of sex: genetic, functional, gonadal, and social. What you are calling man vs. Woman is probably based entirely on gonadal (which doesn't always match the other three and itself contains ambiguous cases like hermaphrodites. And it is true that the majority of cases do fit into cis classifications but that doesn't make them final - the fact that there are exceptions make them emergent. Additionally, social role expectations regarding genders depend on cultural context making them equally emergent and those role expectations carry a lot of weight in the label.

And this is fundamental to all biology. Morphology is what emerges as a result of genetics AND environment. You try to grow a human on the moon, it's morphology and associated functions will be compromised.
