God forbid someone reads a single book, and it is tick

Thru the years I've notices many a peeps that would read a single book and they will really "get on it" in a way. For instance lately, it has been with the ruling elite and Atlas Shrugged by Ayn Rand. I actually have this book but would not read it for many years, while many others respect it more than the bible.
The idea is that first of all I dislike imensly books that set up government and social systems or any of the self-help books. But most of the Rand's fans have read very few books, and when they read such a brick of a book they really got into it. For instance I remember back in the day reading a book called Shogun by James Clavell. It is probably the longest book I've ever read. Altough it was only around 800 pages, they were big and with the smallest font you've ever seen. It literally was taking me 10-15 minutes per page and I am a fast fast reader. It usually takes me a 1:30 for a normal page. Sogun took months to read. I was basically eating and breating Japanese. I've never been to Japan, but after that month and a half I felt like I've spent it there. It is just so wilde, and I've read quite a lot.
So many a times I had this desire to completly put a book first but reading so many it would be rather foolish. As some of those people will find for every Ayn Rand there is a C S Lewis, and the guy that invented Capitalism or Socrates with his Republic. So unless you read those guys as well, you canot get a government/social/economic system for a single book. Especially from a book that is quite simplistic and unrealistic written in a complicated and long-winded language as to conjure up wisdom. But size and setting don't matter in books, just look at a small book that also tought government and where it took us - "The Communist Manifesto." It impressed millions of peasants who only read it and didn't understand anything since the languages and the prose are quite poor as well.
So beware of people that don't read a lot but they have read one book that prescribes a lifestyle or a governmentstyle. Even people just reading a how-to dating book will feel ahead of their peers just for the fact they've read.
