Paul Fassa is a gibberingly insane ignoramus who writes for Mike Adams’s website NaturalNews, and one of the less well hinged contributors there (which says quite a bit). Fassa is, for instance, a “germ theory” denialist. That particular idiocy is the main topic of his own blog Health Maven, which bills itself as an “escape from the medical mafia matrix” (he usually doesn't get in many sentences in before invoking the nazis). As he puts it “We have been taught to fear germs, pathogens, viruses, and bacteria that invade us from out there. This is the Pasteur model of disease contagion. This creates a dependency on Big Pharma to protect us from invading microbes, each having one form (monomorphic) and creating one specific disease […]” Instead, Fassa adopts the pleomorphic theory of disease, according to which microorganisms are the result of – not the cause of – disease. He accepts it because it is not accepted by science and has no evidence going for it, which is supposed to prove that it is not the favored theory of the Illuminati and therefore must be right (by the power of conspiracy). That, and some profound misunderstanding of microbiology, medicine and physiology. It is discussed here.
You may already have an idea of what he thinks about vaccines.
Diagnosis: A walking, talking cognitive disaster. And Naturalnews is sufficiently popular for his nonsense to have some impact.
