False analogy, comrade. 'Redneck' is an acquired (more or less voluntarily) behavioral characteristic, while being a n-word or a kike is an involuntary status by virtue of one's birth. I do not think it is OK to disrespect people because of their birth status, but I think it's perfectly OK to disrespect people who choose to behave in a reprehensible, aggressive and disrespectful of others way. This is the fundament principle of retributive justice.
