I dont like people waving flags when im trying to watch a band but im not going to call them a twat or threaten to rip their throat out, and this is a recent example of the abuse that can be read on the forum.
Totally agree with you that a little respect goes a long way but a lot of the abuse that goes on on here is just good natured banter. I suspect that the examples you cite above were at least a little tongue in cheek, or at least I hope they were. That said there have been a couple of instances of late where I think things have gone over the top. The various ebay and touting threads would be a prime example.
