I don't believe most racism is a result of intelligence but rather cultural diffferences. Given that respectable Africans who immigrate to America often despise African Americans due to their culture, it really depends on culture. African Americans don't really understand African culture. There's also the fact that despite being admittedly a racist, there's plenty of people I recognise are idiotic that I'm friends with but then some very smart people that I hate to be near due to how they perceive the world. After all, if it was all about intelligence then smart blacks would instantly get a get out of jail free card with racists.

As such, I doubt African Americans will ever hate Africans unless mainstream media tells them to. They believe wakanda and westernised perceptions of Africa are truly what their ancestors believed. They don't recognise it was a warring territory filled with slave trade, murder and rape.
