Bill Buckley had just graduated from Yale. His first book pointed out how Yale has failed its undergraduates, specifically in their religious teaching, and overall focus. According to Buckley he said by some as an effrontery or even a protofascist thought.
His point was that since Yale was a religious affiliated university they ought to at least support a belief in God, but instead they went out of their way to teach that Government was the answer to everything and their focus included collectivism, atheism and agnosticism. Yale accomplished this focus 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 had a big influence on Buckley becoming well known for his religious views and a spokesman for conservative views.
