"Troll" to me implies people who try to stir up a fight for the sake of it, especially in situations where there are really no differences that make fighting appropriate. Nothing to do with whether they are members or not.

I can't see any genuine differences in this thread which would make fighting appropriate. Except the differences between people who want to exchange ideas and those who are here to pass out and invite personal abuse.

I suppose if you want to do that it's safer doing it here than down the pub.
