Yes, we all know about some of these street preaching Hebrews. But please don't play the guilt by association game. Because there are extremist in a many religions. This is no different. Yes, we are the biblical Hebrews. Yes, they are black. These two things are fact. All this white people are gonna be slaves stuff is a misinterpretation. It is true is that the nation of Israel (the real ones) will rule with Christ at the helm. You people should read your bibles because Christ's second coming is not going to be roses and cherries. This is what your churches don't preach anymore. The book of Revelation and any books pertaining to the second coming.
Anyway, not all Hebrews believe what these guys are saying. Matter of fact, most don't.
