You seem to keep bringing this back to race.

That's ok too, I guess:

One can indeed, if sincere, discern differences between peoples.

Once you've been in Africa, that becomes clear, not just for sub-Saharan Africans in general, but also between the different tribes:

It is accurate to conclude that e.g. Pigmies are short and Dinkas are tall.

In Africa, you can also see Africans left to their own devices, and observe how they live, manage their affairs, and treat each other.

And in Africa, you can't blame white-on-black racism or anything like that, though some people still try nonetheless, but nobody believes it, not really.

In any case, Africa is educational ... as it may offer a preview for the future of Europe and its (American, etc.) former colonies.
