Most humans almost never actually reason about their cherished beliefs which is why we can reach weird (read, unusual and sometimes extremely politically incorrect) conclusions if we actually take these beliefs seriously.
It is likely that humanity originated in Africa. Hence we can reasonably claim that all humans are by definition Africans. Since we are all Africans all of us should be entitled to settle in Africa.
Hmmm..when we reach this point almost everyone but those to the right of neocolonialists claim that people who have reached this conclusion is extremely racist.
OK, normies. If you do not like the conclusion you'd better modify your beliefs. Just saying…Well they won't ever do that lol. Fuck all normies.
P.S. I'm not actually suggesting that all humans get a piece of Africa. Instead I just love playing with ideas that make all moral zealots mad.
However building a monument in Africa to celebrate the origins of humanity sounds like a really good idea.
