Owning/selling slaves has nothing to do with racism, though. The usage of slaves in the United States also had nothing to do with racism. White slaves existed in America too, they were just more rare because Europeans had generally evolved past raping and pillaging neighboring towns by that point in history, while Africa had not.
In fact slavery as presented by liberals disproves racism, really. Using blacks as slaves is an admission that they are genetically superior to whites for manual labor. Racism would be believing white men are smarter and better at manual labor than black men.
