In my very modest experience, this is wrong. Ignorance is 95% of the problem. Every time I argue with dittohead working dudes, merely pointing out a few facts and putting forth a few arguments is enough to shut them up and set the wheels of thought in motion. Of course, the problem is lack of follow-up; next day, Rush Limbaugh is talking to them and I am not.
A few forwarded e-mails from LBO have already moved a couple of friends of mine a few notches to the left. A subscription to LBO and Chomsky's works _would_ make a difference (what is Extra?).
