I agree, kittylester. I don't see cliques on here either. I see people who have similar views on particular issues, people who, as you say, have things in common, but not cliques.
I think that there are those who think that they are always right, so if more than one person disagrees with them they must be 'ganging up', but that's not, to me, 'dcliqueyness' - it's just disagreeing.
I've never seen intimidation, either. Admittedly, I don't tend to go on the chat threads or the royal family ones, but even so, I can't imagine that they will be intimidating (although I have seen comments that suggest that the RF ones can get heated!). I'm sure that if someone were being intimidated then people would shout up and put a stop to it.
This is a thread about a poster being banned. Whilst I absolutely take WWM's point about those who may also have lost the right to post but who may be less well-known, it would be a pity for it to lose its impact because of accusations of intimidation and cliqueyness that are untrue.
