I do not know why its an ethnic slur. Or why black people find it offensive. I just know it is. And I pointed it out as its an odd choice of a username when really there is the possibility of the creator of that username intending to cause offense to others.
Another part of the article was written by someone of that ethnic minority
John Murillo III, director of communications for the Black Student Union, told the Times. “It takes all the radicalism and activism that we tried to do with the symposium and then [the cafeteria] serves chicken and waffles and takes away from all the stuff that we did.”
I am just pointing it out as its a very weird choice of username, nobody else has picked a meal as their username. But what adds to this is this one is one which has the offensive connotations to it which the story above, while not explaining why its offensive, does confirm it is offensive.
