Well, if science deals with facts, politics deals with illusions. Chomsky is masterful at exposing those illusions for what they are. Not only does that scare the politicians, it also causes indignation among a populace that's very comfortable with those illusions "thanks, anyway, Professor Chomsky". It's only when the government misinformation system go awry (as with Iraq) that people sit up and take notice. Even then, too many are propelled along the party line by a false sense of patriotism.

The point is, people are happy with their illusions/delusions - whether they be political or religious. It's unscientific, it's short-sighted - at it's worst it's genocidal - but it's understandable.
