@mark noble,
No, you're not very good at rhetorical exchange.
You sling abuse about,
you insult others--what you don't do is support a position in a reasonable manner. It's precisely because i am paying attention that this is all so obvious.
I don't purchase other sites. "You guys" don't purchase other sites. The representative of the purchasing organization posts here, if you're interested you could ask that question.
No, it's not a good description. You've no realistic basis of evidence for your conclusion, and i suspect that you are simply motivated by a prissy anger at being contradicted and criticized. And, once again, i have no reason to assume that you are qualified to make psychological judgments of others.
