nikka isn't a degrading term though, so your analogy falls flat.
It isn't? In that case neither is Kike, spick, beaner, fakkit, wetback, gook, etc. Why don't you call your mexican friends a beaner and see what happens? The same mexican friends that you, as a black man, allow to call you nikka.
There is a reason other races don't have a "nikka" equivalent among them and that's because they wouldn't stand for that shyt. fukk outta here.
You fukk boys need to know the history of the word nikka among black people.
