That's a good question.
Jews own, run, and produce all forms of media: Hollywood movies and TV shows, the music industry, news networks, and the publishing industry. They make sure that they obfuscate and bury any information that incriminates them while simultaneously pushing and amplifying anything that paints a negative picture of there biggest enemy: Whites.
There were certainly Whites who took advantage of the slave trade, but their participation was dwarfed by the Jewish involvement.
I know of two educated Black men who came to the same conclusion: college professor Dr. Tony Martin, who has written and lectured extensively on the subject, and Donell Jackson who wrote a book titled "We thought They Were White."
Material from both can be found on YouTube and elsewhere on the Net.
