"black privilege" in play here. White hosts who say nasty things about presidents (especially black presidents) would find themselves out on their ears in short order. Black hosts can pretty much say anything about a white president and get away with it. In reality, black hosts can pretty much say anything about anything and get away with it.
I guess if Hill had wished somebody would kill Trump the ESPN big shots might get a little disturbed.
The fact is black ESPN hosts i.e. Hill, Wilbon, Smith and others make racially charged statements all the time, and nothing is done to them.
