Re: "Name three such books"
On the other hand ...
My Dad caught me reading Marx (Karl, not Groucho) when I was about 12. Instead of getting grumpy about it (this was the peak of the cold war era, people were touchy about such things), he recommended that I get a translation of Mein Kampf, Lenin's works and the newly published English translation of Quotations of Chairman Mao (if they had a copy) next time I was at the Stanford Library. So I did. And discovered these "dangerous" writings were boring, incredibly daft, quite silly in places, and certainly not worth banning. That phase of my life went away in a week or two. Funny how education often has that effect ...
Quite a bit later, I found a scanned copy of The Anarchist's Cookbook squirreled away on a Berkeley FTP site. I printed it out, and Dad and I had great fun finding all the flaws in it ... Yes, I still have all my extremities, and they are still properly attached. Dad has his, too.
