Shaun here. I totally disagree really. Read the entire Ender series and I don't think it in anyway could even rationally be seen as being a Nazi apologist. Unlike Hitler, Ender knew not what he was doing.

But I can see why it could be read as Fascist. Problem is that Fascism, like Communism only really works theoratically. Got a book on Fascism if you wanna borrow.
