You communicate like a Neanderthal, throw stones, carry on like the crudest sort of bestial barbarian, step on feelings, denigrate personalities over and over

I really think Amos went way over the top there. There's no reason to think that Neanderthals weren't as well mannered as you could wish. The rest of the sentence sounds like it's referring to typical Cro-Magnon behaviour, assuming they behaved then the same way some of us do now. But I still maintain that, fortunately, it's the exception in this corner of cyberspace.

I've just had a glance back at the thread daylia mentioned - Violence is the American Way? The interesting thing is a rapid skim through it seems to indicate that, though heated at times, it managed to keep on a relatively level keel. I have a nasty feeling this might not be the case today - and I think that would be down to a very few current regulars who weren't around then.

And I think that one of the things that kept that particular thread civilised was the way spaw set the tone in the third post in: "We are NOT a violent country! You oughta' be shot for posting something like that!!!!"
