Do black people hate cats

Some do and some don't. There are racists in every race. The main reason for African ('Black') hatred toward Europeans ('Whites') is how the Europeans treated Africans back in the day. Africans were slaves to the Europeans.

However, what many people don't know is how Africans became slaves. Most of the time, Europeans didn't just come over to Africa, round up a bunch of people, and ship them off to go work. Instead, they were sold/traded by their own people for supplies and weapons.
