Thanks to the website Open Culture, I came across George Orwell’s 1940 review  of Hitler’s Mein Kampf. Not only does Orwell suss precisely the nature of Hitler’s menace and the source of his popularity, he provides a neat thumbnail description of European liberals and social democrats that could easily attach to today’s American Democrats:
Also [Hitler] has grasped the falsity of the hedonistic attitude to life. Nearly all western thought since the last war, certainly all “progressive” thought, has assumed tacitly that human beings desire nothing beyond ease, security and avoidance of pain. In such a view of life there is no room, for instance, for patriotism and the military virtues. The Socialist who finds his children playing with soldiers is usually upset, but he is never able to think of a substitute for the tin soldiers; tin pacifists somehow won’t do. Hitler, because in his own joyless mind he feels it with exceptional strength, knows that human beings don’t only want comfort, safety, short working-hours, hygiene, birth-control and, in general, common sense; they also, at least intermittently, want struggle and self sacrifice, not to mention drums, flags and loyalty-parades. However they may be as economic theories, Fascism and Nazism are psychologically far sounder than any hedonistic conception of life.
Dig that prescient reference to birth control!
There’s a variety of reasons—see Santayana , Garry Wills , and our own Dan McCarthy —why liberalism leads to force and coercion, but it’s simply not the case that progressivism or modern liberalism or whatever you want to call it is akin to European fascism and Nazism, a virulent outgrowth of German romanticism  that should not be confused with the rationalist-materialist hubris of Marx, Engels, and scientific socialism. Since I began blogging semi-regularly four years ago, the conceit that, well, Nancy Pelosi should check her sleeve for a swastika , has been a constant irritant .
I’m glad to learn that the great Orwell would have been similarly irritated.
