The difference is that you're not calling it "DEI", highlighting the fact that you just use that as a substitute for the n word, considering that all the performers were black and there was no diversity there.

I'm just going by what I'm reading online but to me it seems like a fair assumption that the people crying "DEI", and who didn't mind being in the same company as neo-nazis when it came to who they were supporting politically, are probably racist.
