The Nation of Islam had speakers who made similar references to the satanic racist white man but I have not come across any positive actions that they proposed to change the situation.
When Elijah Mohammad, the founder of this group, died, his youngest son took over but soon changed to more orthodox Islam and moved out of the Nation of Islam. They went on to build schools and colleges to help their community and show that given the right resources, everyone can achieve their full potential. Malcolm X also left that group and became more orthodox and he was murdered.
The Nation of Islam has Minister Louis Farrakhan in charge, no comment!
