2. The Fascists of the future will be the anti-fascists
Did Winston Churchill really say that “The Fascists of the future will be the anti-fascists”? Definitely not.
A similar quote is attributed to Huey Long, a populist Senator from Louisiana, in books and magazines of the 1930s, and 40s: “When fascism comes to America it will be called anti-fascism.” Long was assassinated in 1935 and it’s unclear if he said this, or if it was invented after his assassination. But Churchill never said it.
