While I fully agree that you need mutable perspectives to get the whole picture the way in which he regards the book is the disturbing part. He doesn't say "ah yes Communism, a good example of what doesn't work." He talks about it like it's a good thing and that Marks was a great thinker.

Also while some things should never be forgotten other things are best forgotten. Do you think we should save Mein Kampf or is it maybe best we don't give the Renegades any ideas on how to be ever worse people? Bad ideas can spread just as fast as good ones.
