It amazes me when people see something like this and say it's evil and to burn it.... All it is is a book, sure the man who wrote it was a madman, but the book itself has no capacity for evil. It's history, and a very important part of history at that. Things like this need to be preserved, so that others can learn from them, and hopefully learn to never let anything like the Third Reich happen again. It's a pretty interesting insight into the mind of a madman, but yeah like Bruce said, hard to read....
