Here’s an interesting article about the same musician: https://english.elpais.com/culture/2023-07-21/why-woody-guthries-guitar-was-a-fascist-killer.html
Relevant paragraph:
Woody Guthrie’s guitar didn’t kill fascists because it fired bullets. It killed by neutralizing the fascists. Music, like culture, has the power to defeat right-wing extremists and their antidemocratic ideas rooted in xenophobia, racism, homophobia and sexism. Guthrie fought using ideas, language, music and the shared desire to build a better future together.
Wikipedia cites the book Woody Guthrie: A Life by Joe Klein as a source, but a bit via via. Seems legit though.
