I agree with pr's post and suggest one possible remedy if the software will allow for it: some kind of "sub-moderator" position. Those so empowered could only put offensive posts into "quarantine" for review by full-fledged mod's when they get to them. (Obviously, this would be based on Admin. provided guidelines and a "sub-mod" who used this function because they just took issue with a post or didn't like the poster would forfeit this power).
My current avatar is the new (elected March 30th) Mayor of Paris, Anne Hidalgo
(the first woman to hold the job, FWIW). She was one of the few French Socialists who actually won, on a day the country swung hard to the right.
