Your friends are correct.
I just finished (at 36 years of age) a B.S. at University of California, Davis. It has the unfortunate nickname of "Mini-Berkley," because the liberal/socialist/pro-terrorist crowd is overwhelmingly prevalent.
However, with each class I took, where the hard-left agenda was pushed as the Gospel, I consistantly fought back, in class. Nothing makes a Prof. stick to the facts then being embarrassed by a student who, point by point, dispels their liberal mantras. They weren't happy about it, but I also produced top-notch results, both in tests and the various papers I had to write (Anthro classes were particularly unpleasant, due to having to read so much PC-addled excrement).
While the liberal professors and I butted heads, and they knew me by the sound of my voice, I also won their respect, and have many good references and contacts.
Stick to your guns, make sure your facts are perfect, and don't let them continue with their bald-faced lies...
Of course, I must admit I did enjoy poking a finger in the eye of all the brain-dead liberals... Especially amusing was (during a display of all the PLO "heroes" who were suicide bombers), walking around the campus in a white T-shirt with, in big black letters, "Kill ARAFAT" on the chest... WOW!!! Watch that put a twist in their knickers! :-P
Be well,
