Precisely

'The enemies of intellectual liberty always try to present their case as a plea for discipline versus individualism.... [but] to write in plain, vigorous language one has to think fearlessly, and if one thinks fearlessly one cannot be politically orthodox.' George Orwell

'Political correctness is the natural continuum from the party line. What we are seeing once again is a self-appointed group of vigilantes imposing their views on others. It is a heritage of communism, but they don't seem to see this.' Doris Lessing
