From master historian Jacques Barzun's 2000 tome, From Dawn to Decadence: 500 Years of Western Cultural Life, 1500 to the Present:
Inquisition as such, that is, apart from methods and severity of results, has remained a live institution. The many dictatorships of the 20C have relied on it and in free countries it thrives ad hoc---hunting down German sympathizers during the First World War, interning Japanese-Americans during the second, and pursuing Communist fellow-travelers during the Cold War.
In the United States at the present time the workings of "political correctness" in universities and the speech police that punishes persons and corporations for words on certain topics quaintly called "sensitive" are manifestations of the permanent spirit of inquisition.
