Well, isn’t the “C” in naacp stand for the word “colored”? It’s their acronym, they thought it up. but I agree, let a white person say it and OH MY GOD! You be rassis. Remember the guy who used the word niggardly? IIRC he got fired.
The guy was David Howard, an aide to D.C. mayor Anthony Williams. Howard just happened to be gay, and the gays raised so much h*ll about it, D.C had to offer him his job back. A wonderful story.
