In the Amazon review it says "Wiker has read the worst book in western civilization so you don't have to". Heh, that must be a relief to his readership - ignorance is virtuous. (ETA - I wonder whether Wiker has read them by the way?)
I guess most people would agree that Mein Kampf doesn't have much to recommend it. But it's only in there to provide some legitimacy to the other stupid choices. Other than the Hitler I'd guess they were all worth reading. I'm surprised he didn't revile Thomas Paine, but I think Paine is well-thought of as an inspiration for the US constitution, by people who haven't read him. Personally I love him, but I think reading one paragraph would make Wiker's hair stand on end.
Anyway - can a book be harmful? I actually think it can, but there is no choice except allowing every adult access to every book, because the alternative is even worse.
ETA - I meant to say, are there any books you consider harmful? I'd say Malleus Maleficarum, The (fake) Protocols of the Elders of Zion, The Turner Diaries... not sure what else.
