In what was ultimately a foolish gambit, during the madness of the '60s, the FBI encouraged the most extreme black nationalist organizations in order to discredit and split the left. The more preposterous the group, the better. (It's the same function MSNBC serves today.)

By that criterion, Karenga's United Slaves was perfect.

Despite modern perceptions that blend all the black activists of the '60s, the Black Panthers did not hate whites. Although some of their most high-profile leaders were drug dealers and murderers, they did not seek armed revolution.
