""In terms of language, in my view a word or phrase ceases to be socially acceptable when its common usage become a derogatory term to describe a particular section of the community,""

Which was precisely the point I was making in answer to Brian May's comment about the terms "Paki", "Brit", "Paddy" etc being acceptable.

Given that all have been widely used as pejorative descriptions of sections of society, they (and other similar terms) cannot be described as acceptable.
