Many, many times in my life and my paranormal research I have come across a crass, belligerent and rude psuedo skeptic.
In truth and by their actions, these pseudo-skeptics are defenders of the status quo and materialism. They are fanatics and dogmatists who have no regard for facts, evidence or truth, but have an a priori faith-based belief that paranormal phenomena is impossible and therefore set out to debunk it, not investigate it. And they will distort, dismiss and obfuscate to get their way. Thus, they generally have no objectivity toward evidence, but bigotry and emotional fanaticism.
