I have now read the book and do find it quite persuasive

That said, it explains more the general brutality of the regime & the means by which it was able to garner wide support, as opposed to the specific pathologies & their support by even the rational remnant of the German intellectual class

Peikoff attributes the general trend to general ideas, which I think is hard to argue against

But specific trends and specific manifestations should probably be explained by specific ideas, as I have tried to do above
