The American Conservative, in a review of Jonah Goldberg's Liberal Fascism, argues that the author is not a Nazi.

Conspiracy theories run amok not just among Nazis and anti-Bush leftists but across the political spectrum, doubtless because they have more cognitive appeal than the counterintuitive models needed to understand how the modern world actually works. Goldberg’s own tendency to blame the world’s ills on a handful of evil philosophers from Rousseau to Heidegger is itself a kind of conspiracy theory. That does not make Goldberg an unwitting Nazi.

This tendency to label anyone who's not a libertarian or anarchist (and even then...) a fascist tends to dilute the resposibility of those who were literally dues paying, ballot casting, card carrying, party pin wearing, fascists. That said, there's a tendency amongest conservatives to simply dismiss Heidegger's thinking because he was a Nazi (and because the some French intellectuals read him), whereas his politics can best be described as conservative; respect tradition, do what father says, and so on. On the other hand, metaphysics is a conspiracy to hide the ontological difference from the masses.  ¶ 9:20 AM
