Supplement to my previous post:

we're looking for nastiness not directed at you.

Question, David: are you implying that nastiness is socially acceptable, if directed at me? If so, I would disagree. One can (and should) confine even the most vigorous and sharp disagreement within civilized standards of discourse. Satin put it well:

"swear words were used by people who were too ignorant of the English Language to make people understand their point of view."
