Here's a quote from that link:
My guess is that only a tiny fraction of people truly believes that Armageddon is coming in December 2012. But their uncritical acceptance of this story worries me as a warning of the dangers of our current scientific illiteracy.
We're facing monumental problems with global warming and loss of habitat, yet a substantial minority of Americans thinks the world was formed less than 10,000 years ago and deny that evolution is possible. Many Americans seem to prefer coal-fired generators to nuclear power plants without realizing the toll in public health that coal imposes. Billions are spent, including tax-payer dollars, for so-called alternative medicine with no scientific evidence for its efficacy. And legislators often resist efforts to collect the data that could actually demonstrate which government programs are effective and which ones don't work as intended.
IMO, the writer is simply bemoaning the sad state of scientific illiteracy in this country and how it often leads the uniformed to believe any snake oil salesman with a flashy web site. I don't find his tone to be "hostile".
