If i remember his book correctly, at start he explicitly denies marxist definition of fascism, and then in course of the book his research lead straight to it being correct on at least two separate occasions, them makes full stop and end the topic when he realise what would he have to write next.
I don’t know if thats merely ritually exorcising communism in order to have his book accepted by liberal academia (like in case of Geza Alfoldy for example) or he really is this intellectually dishonest, because he clearly did realised. Anyway it was funny as hell and the book isn’t even bad.
