Dalrymple’s definition of political correctness as “communist propaganda writ small” has been widely quoted across the Internet. In Taki’s Magazine, he expands on the idea:

For the greater political correctness’ violation of common sense, the better—at least if its goal is power over men’s minds and conduct. In this sense it is like Communist propaganda of old: The greater the disparity between the claims of that propaganda and the everyday experience of those at whom it was directed, the greater the humiliation suffered by the latter, especially when they were obliged to repeat it, thus destroying their ability to resist, even in the secret corners of their heart. That is why the politically correct insist that everyone uses their language: Unlike what the press is supposed to do, the politically correct speak power to truth.
