...and the (philosophical) world groans in frustration. Brian Leiter gives it a solid trouncing. 
I am always astounded by the dull refrain of "Nazi! Nazi! Nazi!". Yes, well done, you've spotted the absolutely fucking obvious. Here, have a cookie. Is that really the best you can do? Shout ad hominems about Nazism? Okay then. I'm agnostic on the question of whether or not Heidegger has anything useful to say. I've actually got Hubert L. Dreyfus' Being in the World out from the library now and am using it to plough through Heidegger. But if I simply doggedly refused to read Heidegger because of his politics, that'd be pretty stupid. 
He's claiming that Heidegger is to Nazism as Rawls is to liberalism. Because Rawls, in his defence of liberalism, spent a lot of time talking about ontology, Vorhandenheit, the phenomenal character of Dasein and so on. Knock hells bells out of his ontology, but to dodge ontology or aesthetics because of politics is ridiculous. Read Heidegger in spite of Nazism. Or follow Faye, Romano et al. and just ban Heidegger - empty the libraries of the world of Heidegger, expel him from the curriculum and burn the commentaries. Maybe we could set up a committee to inquire into the ideological purity of those teaching Heidegger. That'll really show those fascists how to be a good liberal...
