I used to have a copy of Life Magazine from the early 50s.
The cover had the picture of “100 American Communists”. It used the term Communist too, not leftist etc.
I recall one was Leonard Bernstein. Before seeing that, I didn’t know anything more about him than he was a conductor.
With artistic talent like that I care not about his politics. It doesn’t change the fact Uncle Lenny was arguably the greatest musician this nation ever produced.
Besides, Gilels, Richter, Berman, Rodhovienskiy, Kondrashin, Sultanov, etc were all Soviet Communists
Lang Lang, Yundi Li, etc. are Chinese Communists
Elisabeth Schwartzkopf, Wilhelm Backhaus, Karl Böhm, Dietrich Fischer-Dieskau, Wilhelm Fürtwängler, Herbert von Karajan, Wolfgang Windgassen, etc, were all Nazis
Who gives a crap? They all made glorious MUSIC, which is all that matters.
