Hey, don't pick an argument with me again
That is literally what the rules say. I however think that this case hinged on the word "negro" even if it's part of a longer lexis. It also states that it has to be meant in a derogatory manner (that's a minefield of context et cetra)
I don't think there is a single person in this thread that can defend that the word "negro" doesn't carry a very negative history certainly in the western world, it's unacceptable to call a "black" person that word. The argument of "It's accepted in my country" really has no legs to stand on in this sort of commission / investigation either (imho)
