Mauf didn’t say that he meant anything else by it. In fact, he specifically said that he didn’t think that. It’s very specifically not an accusation. Mauf was basically giving a gentle nudge you might give someone who used the word “gypped” to describe being cheated out of something, without knowing the etymology. “You probably didn’t mean anything by it, but you probably shouldn’t joke about a black guy gorging on fried chicken,” is a pretty anodyne statement.
