I didn’t claim that this particular division was memetic—quite the contrary.
But the point of my post is that most such divisions are completely arbitrary and have nothing to do with our animal ancestry. Perhaps I should have been clearer and given some examples in the post. Short versus long hair, pants versus skirts, and blue versus pink are among the first few that come to my mind.
Indeed, pink vs. blue flipped within the last 100 years; while short vs. long hair used to signify something unrelated (noble vs. common status) in some societies. And neither is universal.

I agree that those are probably arbitrary/memetic. If such divisions are all your post talks about, then I apologize for misunderstanding.
