I think (but don't know) that Mrzy's comment sounded worse than intended: I believe (but don't know) that Mrzy was quoting from Hair, which is why I suggested in my post that quotation marks were needed. That would have at least given a more clear context to the offensive words.

Is it also possible that she(he?) is unaware that the term in question is so offensive? As we've seen before, there are some terms that are almost universally known and known to be offensive, and others that are well-known and so understood only in certain regions.

Perhaps we'll get an explanation ...
