I've seen this most often in the strident atheist crowd, many of whom appear to be refugees from strict religious upbringings. They haven't actually adopted the open-minded experimentalist approach that science relies on, but have merely switched their allegiance from 'faith in religion' to 'faith in science'.
This was all spectacularly on display when 'junk DNA' concepts were replaced by the now well-supported notion that there is no junk DNA, instead it plays important structural roles in the genome. The atheist argument that junk DNA proved evolution was a random flawed process (hence no 'intelligent design') had become an article of faith in that crowd, and they reacted to the new data rather like fundamentalists react to heresy.
