Where didn't it come from is the better question. Mostly it came from the TV and a miss understanding of history. In short it was because they were told to hate white men, but it comes from everywhere not just from one specific place.
White people built almost every major advancement in modern history, thus they got rich, so it's easy to say they are the fault. A lot of it comes from foreigners who are just simply racist towards whites and were told that it's ok to be racist to them.
