I appreciate Mike Ballard's factual framing (Stein hated FDR's 'New Deal' and praised Marshall Petain's Vichy government) around the provocative title "Gertrude Stein and Moral Rightness."
As to Pound and Stein being of the same ilk--yes they were both Modernist poets and geniuses with right-wing views and you could say both were cock sure of themselves like willful children. However, Stein was a Jew living in Nazi occupied France trying to survive. Initially the French people supported Petain because he was a World War I hero. Stein participated in WWI and was given a medal for her service. By the end of WWII, Stein and her right-winged neighbors no longer supported Petain and they were all participating in the resistance.
Pound, an anti-Semite exercising his American right to free speech, had a radio show in Italy where he lived all during the war. He promoted the authoritarian regime of Mussolini and was paid for these broadcasts by the Italian Ministry of Popular Culture. People who knew Pound said the payment didn't matter to him, he would have said the same thing without the money.
Let's put it this way, sometimes moral rightness can get you killed. In wartime, people tend to bend the rules. Did Pound's behavior look like a survival tactic? And Stein, bending the rules was always an agenda with her. I believe she was politically naïve. A lot of geniuses, including Stein and Pound, have done things that do not sit well with ordinary folks.
