[Antoninus]

What a garbage book.

This book was (and is) a vehicle for introducing young people to obscenity and "alternative lifestyles"--and making them seem normal, at least in comparison to the occasionally judgmental but always hypocritical main character. The amount of pointless vulgarity and blasphemous language contained in The Catcher in the Rye is so overwhelming, even by today's standards, that the reader quickly becomes numb to it. It was apparently one of the first mass market books to incorporate the phrase "f--k you", and no doubt that made it immediately attractive to those with an agenda of breaking down societal standards.

That’s silly. If you read Salinger’s other work, it’s about characters seeking spiritual sustenance. There is nothing Marxist about it.
