In some cases, such divisions are actual - males and females actually do work differently from each other, beyond reproduction. The brains develop at
different speeds and tend to emphasize different areas, emotional responses tend to differ, etc.
Race, however, is utterly irrelevant, beyond some medical conditions (lactose intolerance, sickle cell, etc). The division here is entirely cultural.
Culture, with all it entails, is the big divide between humanity. And it is one that will never be overcome, simply because humanity will always work
on a "tribal" level. Even were there to be a singular world culture, it would break apart quickly, as different areas develop different needs and
preferences, etc.
