The campaign is not really against "whitey". It is about communism and revolution. The white leftists behind much of it want to use the blacks in much the same that Charles Manson wanted to with his failed "Helter Skelter" plan. They, like he, wants them to do the dirty work. Then, if they should succeed in the overthrow, they (the white communists) would take over from the blacks.
Todays white communists are no smarter than what Manson thought the blacks were
