My answer to the OP is:
it is judgmental to make any assumptions / value judgements about names. They are all subjective, we all have personal preferences but it is obviously provocative to ask whether a particular name is the ultimate representative of qualities thought to be derogative. As 'chav' is.
You are being disingenous in the way you insist that you have asked a qestion, rather than made a statement. The implication of your question is that if not this name, then some other is the 'no 1 chav name'. Which is judgmental and derogatory. And would be equally judgemental and derogatory if it was 'no 1 ponce name', for e.g.
Personally I think labelling peple as chav is horrible. It is intended as an insulting term, and used as such.
And it all adds up to a horrible thread.
