Its way too oversimplistic to say the 5 percenters as just "thinking whites are the devil." They were an off shoot of the nation of Islam in Harlem and who sought to educate and raise up the blacks in the city. Science and math studies, mans relation to the practical and spiritual world were focuses. Develop yourself and open your mind, something of a will-to-power-and-truth. "Dropping science" comes from them. Yes, they said that God was black and that blacks were the "true" humans. This was based on the out-of-Africa realities of our human species. Was there hatred for white people? Well developing in 1960s New York you bet your ass there was something to that.
Jay-Z saying he believes in there organization "a little" doesn't mean he is some hard core racist. Their tenets entertwined with the development of hip hop, Wu-Tang in particular used a lot of their language. Jay Z can respect that history and some of the teachings without automatically being assumed a virulent racist.
Okay, rant over. Just wanted to try and and explain it a little. I'm sure people are going to believe what they want, but wearing a medallion and saying you agree with some of it is a lot more complex a thing than Sterling saying blacks are treated like dogs around the world and I don't want to change that. Very different situations.
