The most harmful books

Kristian Köhntopp links to an article of Human Events, some conservative newspaper, who asked a panel of 15 conservative scholars and public policy leaders to help them compile a list of the Ten Most Harmful Books of the 19th and 20th Centuries. To summarize what is harmful for conservatives: Marx, Engels, Hitler, Mao, The Kinsey Report, "Democracy and Education" (WTF?!), feminism, positive philosophy, Nietzsche, Keynesianism. That's basically the Top 10. On the "honorable mention" list are books like "Introduction to Psychoanalysis" by Sigmund Freud and "Descent of Man" by Charles Darwin. Obviously, this panel outed themselves to be one of the most anti-progressive and anti-intellectualistic bunch of people ever.
