“Throughout much of history, free speech advocates have been progressives fighting elite power structures. Karl Marx rightly opposed and indeed lampooned press censorship. It is a tragedy of the 20th and 21st centuries that too many progressives have switched sides, weaving poorly reflected theories of language into poorly reflected theories of politics. Jacob Mchangama leads us through a vividly told history that, sadly, continues to repeat for as long as its lessons remain un-learned”.
