Re: "creating a free speech czar"
Some of Enid Blyton's books were banned due to racism. In the Noddy books, for example the (black) Golliwogs were always the villains. And the various groups of children (with or without dogs) were invariably middle-class and the villains working class. Also, the descriptions of caves were generally geologically incorrect. (I'm not a geologist, but heard a radio show several years ago when a (working-class) geologist explained why he banned Enid Blyton from his home, not due to the classism, but the awful geology.)
