If the lesson you draw from the history of far right authoritarianism is that being nicer and more accommodating to fascists makes them less likely to do harm, then you’re an idiot.
And if you think “those weren’t fascists, they were Christians and Patriots” then you know nothing about the history of American fascism.
Here’s an old thread on Gerald LK Smith, who headed a “Christian Nationalist” party called, wait for it, “America First” in the 1940s and 50s. Some of his ideas and rhetoric might sound familiar. https://twitter.com/sethcotlar/status/1198307146749763585
One of Smith’s big financial supporters was a wealthy heiress, Countess Guardabassi, who carried on a friendly correspondence with neo-Nazi Revilo Oliver in the 1960s. She wintered in Palm Beach, FWIW. https://twitter.com/sethcotlar/status/1258993728808554496
