How dense are you? It was his thread in the Knifemaker's forum. He can say whatever he damn well pleases as long as he's not a bigot. Knifemaker's tend to get a bit of leeway in their forum since without them there would be no knives. As for proof, he has seen the guy in action on a different forum and he stated so. That's good enough; don't like it, go somewhere else. This community stands behind Knifemakers and kicks out trolls and their support crew.
There's a famous old saying: if you don't like something, change it. If you can't change it, change yourself. Translation: 321 is long gone and not thought well of around here. Nothing you could ever say or do will change that so perhaps you might want to change yourself.
And quit SHOUTING at us! It's hard enough to read your point w/o all the yelling.
