Bill Whittle offers a long post that is nevertheless worthwhile when encountering celebrity Rosie O’Dim, or in my case an old Army friend I hadn’t seen for thirty years when we exchanged email in 2002 and I discovered he thought space aliens were already here and controlling the government and us. Whittle thinks these people are far more commonplace than we know:
"What I am trying to do here is to build a chain of evidence to show a progressively deteriorating epidemic of world-wide insanity, of truly diseased thinking — not just a misunderstanding or difference of opinion but real, diagnosable mental illness. I want to get to that disease in a minute — and the cause of it too – but first let’s examine what some people claim to believe in and the mountains of sand one has to carry in order to bury one’s head so deep." (Whittle’s emphasis)
Instructive, and entertaining. Via No Left Turns.
THE TEXAS SCRIBBLER 
I read almost all of Whittle’s post. I agree with all of it and have tried myself to convince some nutbars (defined as anyone who believes in that sort of assorted crap).
I don’t bother any more. I know it is dangerous, like he says. Hell, look at the silicone breast implant stuff, the Agent Orange stuff. Junk science is costing us a fortune.
It is a losing battle to try and improve the logical processes of the human animal. One of the best evidences of that is to simply look around at the people we keep electing to high offices.
Read through to the end and you discover he’s blaming Hollywood for movies such as Oliver Stone’s JFK fantasy, and celebrities such as Rosie O’Dim with her “fire doesn’;t melt steel” brilliance, who haven’t got enough sense to get out of the rain yet have many followers.
