You were skirting it, but that's all right, even necessary. Diversity of opinion, loyal opposition, due diligence, reality check and all that.
These people aren't just over the line. They're beyond recall. It's almost like a mental illness. There's a guy calling himself ucblockhead who's just barely this side of full blown sociopathy. You can't be a reality check if you're utterly divorced from reality. And there's nothing loyal about this kind of opposition.
