Stanley Kurtz has a review of Evan Coyne Maloney's documentary on political correctness run amok on college campuses:

I was struck by the scientist who said that her students were able to figure out her politics simply by noting what she did not say. Just by teaching her subject, without adding extraneous leftist political harangues, she had revealed herself to be a closet Republican. You won’t believe what happened when the faculty found out about her politics. But the full horror story is almost less disturbing than the reality of that single observation about silence. Particularly in some of the non-science disciplines, it really has gotten to the point where mere silence on matters political is enough to reveal you as the enemy.

It's ironic that these are the people fondest of throwing around the epithet "fascist."

Go tell the film makers that you want to see it. It's particularly important to get it shown on the campuses. Check out the trailer, too.

I want to see it but who the flink goes to a theater for this sort of film? Making it available as a DVD might help.

I try very hard not to let discussions of politics creep into my classes. I teach chemistry (and biochemistry). You wouldn't figure that there would be any room for politics (in this respect I also include religion) in such subjects, but there are. For example, when I teach biochem, I always choose to make a statement at the beginning of the semester that they will be hearing the word "evolution" a lot and that they need to get used to it. I am not challenging anyone's religious views, but much of our understanding of biochemistry relies on the concepts of evolution. To the best of my knowledge no student has ever complained about it. I did, though, point out to my gen chem class the other day that H2O is a much better greenhouse gas than is CO2 (this in the context of Lewis structures), and got a few knowing looks from those in attendance.
