Your comment raises a very delicate point and I'm not sure that I am tactful enough to make it clearly.

Zooming out to get a broader view so that we can notice what usually happens, rather than the memorable special case, we notice that most Germans were enthusiastic about Hitler, all the way from 1933 to 1941. It is hard to reconstruct the reasons why. Looking at the broad picture we get a clear sense of people being their own worst enemies, enthusiastically embracing a mad leader who will lead them to destruction.

The message that history is sending to Alan is: if you had been a young man in Germany in 1933 you would have idolized Hitler. There are two ways to respond to this sobering message. One is to picture myself as an innocent victim. There were plenty of innocent victims, so this is easily done, but it dodges the hard question. The other response is to embrace the LessWrong vision and to search for ways to avoid the disasters to which self-deception sentences Man.
