I  read Huckleberry Finn in high school ( circa 1965 ) . Mark Twain 's famous novel was certainly " friendly " to the dramatic civil rights movement in America at that time. A few years later I was inspired by Mark Twain's anti-imperialism and quoted him in a published letter opposing the Vietnam War: " In America we have those three precious things: freedom of speech, freedom of conscience, and the prudence never to practice any of them ".
Right wing talk radio in Rhode Island is always associating the more ridiculous forms of " political correctness " with some generic LEFT. For years now I have associated identity politics -often vicious, narrow minded, and punitive- with a degenerate " illiberal liberalism " that has completely retreated from class struggle issues.
And you would think that very fragile left wing organizations would be in the vanguard  of any FREE SPEECH movement .
The experience of my life is that TRUTH itself is invariably subversive. And what exposes the SOCIAL LIE more effectively than great literature ? What literate young people today might like to read is an American equivalent of Celine's " Journey to the End of the Night " - reviewed by none other than Leon Trotsky.
One wonders if American capitalism is too rotten to die ( it needs help here ) .
