Farrakhan has been saying this for decades. It is just more of his loony nonsense.
Anyway if he does want a 'Black State' where Blacks rule, all he and his followers have to do is to move to South Africa. They are doing everything he claims he wants to do. They are forcibly taking property from White people and are essentially driving Whites out of the country. What he claims to want already exists. All he has to do is to move there. But we all know that will never happen.
Like the Leftists, Blacks bitch and complain about how 'evil' America is, but they NEVER just LEAVE.
