Chinese girls pretty much mostly like just Caucasians and other east Asians so their preferences are not even relevant here.

First things first, sub-Saharan Africa developed differently from the rest of Eurasia. They have tropical diseases to contend with, they don't have domesticable horses and other beasts of burden (despite appearance, zebras are impossible to domesticate, as later European settlers found out), etc.

They were cut off from most developments outside because of the geographic barrier. Given enough time and non-hostility, they could have caught up. Look at how many native American quickly took to horses and firearms after they were introduced.

Also, we can't make light of the effects of the slave trade. Sure it's mostly Africans that engage in it and they've been selling to Arabs before but the huge demand for slaves in the New World drove slavery to an industrial level. It got so bad in some places that even petty crimes was punishable by slavery, so that the offender can be quickly sold off.


There may be differences but I think they are slight and can be compensated with education, etc...


Now this is just mean. "Not even human"? This is the sort of belief that leads people to murder others and feel no remorse for them coz, you know, "not even human".
