The word "troll" seems to generate heat in itsef,possibly because it refers to a method of bait-fishing and also a nasty thing thatlurks under bridges; and people seem to use the word sometimes with a flavour of one original meaning, and sometimes with the other. I am still a little mystified with these sort of discussions, but I've only been visiting for a month; does it all become clear eventually? I have identified some seriously barmy nasty postings.Are they trolls? Or are they just people I violently disagree with? And, frankly, does it matter?
