Bruce - in the wise words of St Sen of Mudcat...

"The analogy of playground fights and teachers reminded me of my days on playground duty. I couldn't have ignored the spats, sent the children elsewhere or banned them permanently from the school. I sometimes did try diversion tactics. (Initiate a new game or give one or two a wee 'job' to do for example)
But the folk on here are NOT children, and could surely moderate their remarks and state their views without becoming abusive, belligerent and insulting."
