Bill Buckley has just graduated from Yale. His first book pointed out how Yale has failed its undergraduates specifically in their religious teaching and overall focus.
He felt that since they were a religious affiliated university they ought to at least support a belief in God but they instead they went out of their way to teach that Government was the answer to everything and their focus included collectivism, atheism and agnosticism.
This was accomplished by the choice of classes offered, textbooks used and instructors bias.
The book was a bold statement accompanied with names of instructors and examples. It was his first book and he was on his way to being well known for his religious and conservative views.
