The problem is deeper. Its start earlier in schooling.
In fact, it is schooling.

Govern-cement schools are not about teaching, they are about schooling. Getting all of the little fishies to swim in the same direction from the same stimulus.

The primary agenda of schools is to propagandise the children.
They are taught opinions as facts. And then they have these "facts" tied to their view of themselves. They are a good person if they believe these "facts".

So, when a student gets to college, they are a child. They have never been encouraged to grow up, in fact their growth has been retarded.
On top of that, college today is only to waste 4 years of a kids life to postpone their entry into the job market.

When you are brought up in that, the TRUTH is the enemy. Since you have not been taught how to think, only what to think, and that is tied into your self image, any attack on those "facts" by exposure to the TRUTH is like sunlight to a vampire.
