Ah, that's the justification. I've never understood the official Russian "denazification" position; it should be clear to them no one now or ever is going to take it seriously, why continue with this absurd pretense?

That said, in this case it's more barbed than the article suggests. As part of denazification, the Allies did destroy books. To suggest book destruction is what typifies Nazis is absurd unless we also call the Allies Nazis.

> As a consequence a list was drawn up of over 30,000 book titles, ranging from school textbooks to poetry, which were then banned. All copies of books on the list were confiscated and destroyed; the possession of a book on the list was made a punishable offense. All the millions of copies of these books were to be confiscated and destroyed.

That said, Aztec culture was full of horrors we can now no longer even imagine, paling even before the Nazis. To the extent the destruction of codices was deliberate, much of what went on would have seemed to be a relatively necessary de-Aztecification.
