I often watch one of the HI sites, and there are three attitudes that I see with alarming frequency:
A) "I don't know anything about this, but it just can't be right;"
B) The corruption inherent in being absolutely without any check or restraint upon ones' "power;" and,
C) An almost gleeful desire to cross over into offering opinions about pure design issues - even as far as critiquing the paint scheme.
About all you can do is say "He's wrong. There is no problem. I have the license to offer an opinion on this subject. He does not."
