re: Misquoting Henry II
That would be meddlesome, not 'turbulent'... No matter - the important point is: You don't want a Beckett-like outcome. Thomas a Beckett was considered a martyr, and later made a saint.
While I agree with you (and Chris and "Buster"), the solution you have for "bmp" and "Sam" should work for all. In some circles, it's called "not dignifying the utterance with a response". In others, it's called "stop giving the trolls what they want."
Difficult, I know - but consider it a not-insurmountable challenge to your self control.
