First of all, lets put to rest the little fallacy that conservatives somehow get silenced on college campuses. Someone forgot to inform my math professor of this undeniable "fact".
Second of all, this man stood in front of a class of pretty impressionable 18/19 years olds and completely misrepresented science. And he literally told the class, "This is the way you should think concerning this issue." Not one single liberal professor I have EVER HAD has done that. They might say, "This is my take on this issue." But it is always, always, always followed with an exortation to apply and develope critical thinking skills and investigate the facts for yourself.
Yet, I read on this board, and in other places, over and over again, how the "liberal elitist professors" tell people how to think. It ain't the liberals doing it. At least, not on my campus.
