I think I'd choose the word ignorant over idiot simply because they're programmed by the media, on prescription drugs, drink fluoridated water, have chemicals sprayed on them from the skies, eat gmo foods and are called a conspiracy theorist by their peers if they even ask questions.

And if they come out of the fog enough to dig a little, cognitive dissonance kicks in and they shut down because the truth is too overwhelming. It's a wonder anyone is awake at all.
