I have three degrees, so needless to say I was at university far too long. I saw Christian organizations speak. Prayer at graduation ceremonies (mine was led by a Rabbi) and we had very strong ROTC programs.
I had a professor (a Duke graduate) who made a point to make "Billary" jokes at the start of nearly every class. He also was an advisor who told a good friend of mine that she would have to give up her career once she got married because that is what the Bible said.
I had a 5' nothing professor of history, a Yale graduate, who was an officer for the Marine Corps in Vietnam. He was one of the most leftist professors I've ever had. He taught a great class that analyzed the history of modern revolutions (starting with the American to the present - well, present at that time).
We had all kinds of great speakers come through. I would say that I was prescient to have taken a series of religious studies classes on Islam, but it was probably just blind luck. I was interested, so I took them. The teacher was an American woman who had lived in Yemen for years and spoke fluent Arabic (which she also taught, but I wasn't that brave). I learned a great deal about the religion, and as with Catholicism or Judaism, the myths are often lies that have been repeated over and over throughout the centuries. The truth is far less melodramatic.
I had a number of great Economics professors ranging from right wing to left wing, to just damn good teachers.
My point is that these caricatures of American universities that are most often painted by the right wing, are built upon a few anecdotes. They don't seem to measure up with reality. If you are at the university level and you have no critical thinking skills (and yes, I used that term) and you are just a sponge to mop up whatever you are told - then quite honestly you have no business there.
Likewise, if you are there just to take classes, graduate, and get a job...then you have no business there. That's better left to a community college or tech school. A university is about growing up, living on your own, and learning a lot - about a lot of different things. People who don't take advantage of that and beat a narrow path are wasting their time, in my opinion.
