There are segregationist beliefs among black activists from groups like Nation of Islam that portrays black people as being an enlighten superior race and white people as being subhuman creatures created by an evil scientist named Yakub to destroy the ancient Black Utopia. Mormons were severely criticized for analogous beliefs that for the most part were abandoned since the 1970s.
Black Panther was an important movie because it shows the closest thing to activist's beliefs about Africa being a "Jetsons-like" society before white people invented slavery.
Just summarizing that claim some activists try to push about black people being members of some ancient royalty before being captured by "The Whites" to become slaves(because white people invented slavery). There was no such thing as negotiations with local kingdoms or purchase of slaves from societies where the concept already existed. It was just a futuristic society living a utopia until a couple hundred white sailors with vitamin C deficiency kidnapped every one they could to force them into slavery.
It's too complicated to explain the whole nuances about foreign kingdoms, slave societies, isolation across the World in medieval times and the whole societal organization of African Sub-Sahara kingdoms. It's easier to put the whole thing as bad whites invaded peaceful monolithic societies and enslaved everyone they could find. And many times it is complemented with the idea that most African slaves are members of African royalty(just like when going to a Medium to do past life regression, the previous life is always a king or queen, and never just another homeless peasant or slave who died by plague or starvation. Everybody always have royal blood.
Even today in my country we have two black figures who fought slave owners each their own way.
One came from being an illiterate nobody who learned how to read by himself and got his freedom due his argumentative talent, becoming one of the most important intellectuals of Brazilian society and freeing over 500 slaves in courts without bloodshed. His name was Luis Gama and his target was the institution of slavery itself.
The other was the grandson of a Congolese military leader captured after the defeat of the Netherlands in a war against Portugal. His family managed to escape and form an enclave called Palmares were they recreated portions of their former Congolese society before the whole thing was brutally destroyed by local powers. His name was Zumbi and his social main goal was the survival of his small kingdom, which also was a slave-owning society.
Between those cited above, Zumbi is far more celebrated by black people in Brazil than Luis Gama as an icon of anti-slavery. Probably because according to the stories, Luis Gama started as an illiterate slave and a nobody who built his whole life by himself as a black man in a very racist 19 century society while Zumbi was supposedly a distant relative of the Congolese royal family. The worship of nobility seems to happen in every human society. But the reason mostly cited was the "lack of blood" in Luis Gama's methods to fight slavery while Zumbi's men fought to the death against white slave-owners to take for themselves the slaves. Although the quality of life of a slave in Palmares was far better than with their white masters, they were still slaves. Zumbi being more celebrated comes also from an old human desire for revenge even though he was not fighting for social change but for his enclave.
The main reasons I find for Zumbi being more appreciated as a figure of struggle against slavery in Brazil is a mix of the appreciation for royalty with the desire for revenge, with some posts from activists criticizing Luis Gama specifically for his methods sparing the lives and social positions of the former slave-owners from which his clients were freed. I recognize it doesn't look like a happy ending when the villains don't suffer anything, but the real life is not a fairy tale with "good Vs. evil"
