"...clearly the greatest and most influential novel of the 20th century"
Orwell's 1984 has sold over 10 million, Tolkein's The Hobbit: 100 million, Tolkein's Lord of the Rings: 150 million, The Da Vinci Code: (unfortunately) 55 million.
Atlas Shrugged is not the most influential book written in the 20th century, based on common benchmarks like popular references and number of copies sold. It may be a wonderful book, but the propaganda stated here is over the top.
If you're gonna say it, be prepared to defend it. The collectivist libs play the popular media like Satan's pipe organ.
Well, at least check this out, FWIW:
