Every Jags forum (no doubt just about every football forum for all I know) is or was full of posters who say one thing one week then something near the opposite the next. I'll be as guilty of that sort of hypocrisy as others.
The other side of the coin is posts by folk on a kinda agenda (not so guilty of that, I don't think ) but again just the sort of thing you surely expect on any forum.
In some aspects the forum represents the pre and post game pub patter. It would be a dull and rather strange pub that had a clientele who never varied their opinions and only spoke when they were stone cold sober so as not to offend by uttering something contrary to whatever they were saying the last time they were in. Stretching the pub analogy a bit further every bar will have punters who take themselves a bit too seriously, low level hypocrites, snobs and even the village idiot (who I notice hasn't yet posted on this thread, yet) .
