Some did go back but many didn't because they had no means to go back and they had nothing to go back to. What do you think happened to all the children born in slavery? They had no home. That was taken from them. That is where most of our people in this country come from. The children of slaves. Dancing around this is just a cop out.
We must understand, they know they are wrong so they must either deflect, gaslight, half truth or outright lie depending on the conversation. What this meme doesn't say and any white boy saying this in a debate in front of people can't counter is this fact.
If we take the meme to the point of you didn't go back once freed. He knows he leaves out the fact that part of the institution of slavery was to strip blacks of not just any knowledge of their past, by design, the only narrative they have of Africa is a negative one from them. Slavery made it impossible to go back by design. White historians know this.
Furthermore, even if Blacks wanted to, they had no money, knowledge or any resources to go back there and succeed. Furthermore, Blacks were tied to the land they worked on, understood. Its an asinine meme but when its passed among each other on white racist sites they make it make sense to themselves, they lie to themselves.
