Marvel has history of publishing extremist "Black Power" comics.
In 1966 Marvel began a superhero known as “Black Panther.” He appeared in various comic books and graphic novels. Today Marvel began co-producing an animated version of Black Panther with Black Entertainment Television [BET] in 2010.
The Black Panther character is explicit pro-black and the comics are viciously anti-white.
Black Panther is T’Challa, the king of a secret African nation known as Wakanda. The inhabitants of this nation keep their lands hidden from the white man so it is not “exploited” for it’s mineral wealth. T’Challa’s father is murdered by a white man who becomes Black Panther’s main enemy.
His other principal enemies are the “racist” South African government. Particularly South African Magistrate of Communications Anton Pretorius. This character kidnaps the Black Panther’s mother and sexually abuses her. Imagine for a second if any comic book depicted the same thing with the races reversed.
Black Panther is a “genius,” who has a Ph.D. in physics from Oxford. He also keeps it real by having a harem of “wives in training.” When not fighting “racist” South Africans, he comes to the USA to fight the Ku Klux Klan.
So Marvel has a history of publishing an explicitly black racial hero who fights “racist” whites, and began co-producing an animated version with an explicitly black cable network in 2010. Three months after Marvel first debuted the Black Panther, the militant Black Panther Party formed using the same name.
