Why'd you leave the most notable one out of your list?

I don't think that one was ever "acceptable". That being said, literally every term after/including "African-American" in that list is socially acceptable. Not sure what they're going on about.

I'm not so sure. It sure gets used a lot in "Huckleberry Finn", even by people who aren't being malicious. (From my recollection, anyway. It's been ages since I read it.)

The current norm is that it mustn't be said, even in a discussion of that class of words.
