NeveraDub,
"For 20 years I listened to talk radio in the U.S., being indoctrinated to see the left just as depicted in this movie."
Twenty years of Rush Limbaugh, Michael Savage and Matt Drudge? Just shoot me.
I avoid nut jobs of any persuasion, liberal, conservative, religious, conspiracy theorists, or psychotic girls (unless they are really, really hot). Having said that, I have found it much more difficult to find left wing nut jobs; I rarely stumble across them.
I've taught at two colleges, and my experience is vastly different. We had a few right wing nut jobs. They didn't fare well as could be expected in a collegiate environment. But I do not recall any left wing nut jobs, and the focus of both colleges was to have open minded, fair and respectful discussions about all topics. I kept my personal political and religious views to myself; I believe most of the other profs did the same.
