I mean, that is, pretty much the line of all Black Nationalists going back to Marcus Garvey. But is a generalization.
The bigots on this site like to think that the black community is of one mind, as if the white community is.
Garvey received condemnation for such views from Du Bois, so. . . this is, IMO, just an excuse for Anti-Americanism and hatred.
On top of that, culturally, Garvey wasn't really American, IMO. Being born in Jamaica, and having been in Britain so long. . . I am suspect that he was as much a British agent as a black nationalist.
But. . . there really is no denying the HUGE following, historically, of Garvey here in the states.
