fear and ignorance is usually what leads people to such black-and-white views. So yeah, childhood culinary conditioning trauma leading to aversion, supported by machismo and selective deafness to all media where nutrition is concerned. (Some geeks restrict themselves to a very narrow band of information and thus, despite being connected like never before, and having potential access to so much information on every topic, they remain blissfully ignorant of a great many things. Like vitamins.)
