Whether it is pedagogically institutionalizing blood libel:
The new PA history books, among other things, present the infamous anti-Semitic forgery produced by Russian police The Protocols of the Elders of Zion as an accurate portrayal of the decision of the First Zionist Congress.
Or trying to dimiinish the supreme wickedness of it:
German prosecutors have provoked outrage by ruling that the 1945 RAF bombing of Dresden can legally be termed a "holocaust".
The next holocaust seems not quite so far away as "never again" would dictate.
