Was it the school you went to?
My college was pretty straight forward middle American values. I even had a professor in Animal and Veterinary Science that made us look up agricultural practices in the Bible. I liked that. In a university there are many required classes in various colleges. Then you have electives. The downtown colleges were all pretty liberal in the sense of not agreeing with a Biblical world view in some cases.
For electives, I took classes that I thought would be practical for my plans. Some just ended up being a challenge, for example English writing class. My professor made us write papers on controversial issues, abortion, suicide, animal rights, and my term paper was on Evolution vs Creation.
I took the Biblical viewpoint and the teacher always took the extreme opposite argument. We had to defend our points of view. It was good for me to be challenged. A man has to learn why he believes what he believes or he'll fall for anything.
