Regrettably this attitude is as common as fleas on a dog on most American college campuses. It is all sophmoric, sanctimonious drivel.
The problem is also self-perpetuating. These idiots got their Masters and Doctorates by aping the anti-war & anti-American line when they were in grad school. Now, the only students who have a chance under them to get high grades through grad school are the ones who also repeat the same crap.
Any student that doesn't "toe the line" as far as anti-American crapola goes doesn't stand a chance of getting a post graduate degree in the Liberal Arts. So, the next generation is going to hear the same crap. I have no idea how to counteract this.
