Your comment makes me think that we have criminalized and squashed entertaining but obviously political writing out of existence :-) .

Say that somebody writes to make certain ideas more visible. For example, somebody wants people to buy the idea that amusing oneself to death is what we do (the book you mentioned). Somebody else perhaps has found that we are chronically depressed and cynic, when instead we should be thinking that a dead death itself is a fine trophy to hang on the wall during the march of progress[^1].

You can a) decide that you are set on your ways, thus entertainment should be pure and removed enough from reality so it doesn't mess with your deeply held beliefs and not read any of those books. or b) run the risk and read the thing with an open mind.

A lot of people are in the a) camp. Those who are in the b) camp would still like to be entertained a little.
