To be honest I can't say I've ever noticed anything of that kind on this forum. Sometimes you can see that some are pretty passionate about their views, but I've never seen anything nasty.
I've always been treated really well, even though some may not agree with my views. It's all about giving and receiving respect, which I think is generally the case on this forum.
...Apart from TxKimberly giving me a hard time (several broken bones and a black eye), I really have nothing to complain about
PS:... and even then, she was kind enough to visit me in hospital.... although I did fall violently ill after eating the grapes she brought me......
