I try to raise the level of this thread but it remains miserably low, as batrachians brain, somewhere there.
The Rossi thread has always been contentious, but not because of the Bruce H comment you use as an example. He actually made one of the few science based points I have seen.
To be honest, I can not see this conversation ever becoming more civil. Those against Rossi have legitimate grounds for their anger, and his supporters are very protective of his antics. That makes for an explosive mix, and unless Rossi actually produces something credible, I see nothing that will change the situation.
The staff recently debated shutting down the Rossi thread to up the quality of the forum...which has been trending down in quality lately, but decided it's overall contribution is still positive. But it was a close call.
Many times over the years we have cautioned those who decide to post here to have a thick skin. I always say "check your ego at the door", meaning do not take it personal. If unable, then this thread should be avoided.
