Of course, you left out one important characteristic. Once he has seen that he has hopelessly screwed up in facts or whatever, he just disappears with no further comments, hoping everyone will forget until the next time. It does get old to see such blanket statements made, giving new CC people the idea that he not only knows what he is talking about, but that what he says is gospel truth. That's the real danger. Being a master of misinformation and excuses doesn't help anyone.
