I really can't see how commenting that it didn't take long for a positive thread to become negative can be construed as me 'trying to stop people expressing THEIR opinions'. It was a comment expressing MY opinion, just like all the others. I did not think anyone was trying to shout me down. But this is why I did think that, perhaps, there was an element of some opinions being given more encouragement than others. I have been told that this is not the case. My experience has been different, but I accept that. I made a comment, only a short one, and one which was 'off-the-cuff'. All I was saying was that it didn't take long for the criticisms to come. It was nothing more than an observation, if you like.
As it happens I don't think that the purpose of a forum is to start a debate, but to express opinions, share information etc. Yes, it's a good place to post complaints about service, or products and so on. I don't necessarily think it's the best outlet for people to make personal criticisms, but okay, if that's what people want to do. I do find it a bit sad that as soon as someone says something positive about a presenter they are immediately countered with less than flattering comments. Perhaps I have missed the point? That is why I said perhaps a forum was no longer the 'place' for me.
As far as I can see this thread has not 'turned nasty'. I certainly have not been nasty, and I haven't seen where anyone else has been either! I'm all for robust debate but am sorry that this thread, which was clearly started with such good intentions has become something else.
And finally, and this may well be absolutely final for me, I would never dare to suggest what should and shouldn't be allowed on this, or any other forum. There are people already doing a great job at that. If I had serious concerns about postings/behaviour on here I would, as you suggest, take it up with them. I do not. I am appalled that you have somehow gotten the impression that I am that arrogant! I had hoped that my comment might make people think before they routinely disparage individuals (presenters & guests etc) in such personal ways. That was all.
My small comment, for whatever reason, seems to have been taken as out of place, while others are simply members expressing their right to an opinion.
