Person #1: “I look at you, and I immediately think of one of the greatest athletes of all time.”
Person #2: “Why you gotta be so racist, man?”
If Donaldson was sincerely comparing him to JR, one of the greatest Major League Baseball players of all time, it would have been fine. It’s because Donaldson was being snarky that there is an issue. So this is not racism, it’s within the normal range of trash talking.
