This post is embarrassing, this is your rebuke of what Zizek lays out in that whole chapter? You imply Zizek is acting as an apologist for Heidegger because he seeks to locate some form of continuity between his philosophy and his Nazism, between his fixation on 'authenticity' and his celebration of Nazism as an authentic community?
You're not getting it. Heidegger's fixation on authenticity didn't just descend from the heavens in order to confuse Heidegger into become a Nazi. Zizek is looking at philosophy in order to describe an individual's politics. What's wrong with a good old fashioned political analysis of politics that adresses philosopchical issues as and when it needs to?
It's obvious that Zizek is trying to rescue something of Heidegger's. But what if the most interesting part of Heidegger has the most obnoxious political consequences? All this seperating out the good from the bad in Heidegger is fundamentally philistein. And yes it's an apology for Heidegger - it's not his fault it's the bad elements in his philosophy's fault.
