I remember a story on the actor Sterling Hayden.
He actually joined the Communist Party and on the same day bought a yacht. He said he loved money but for time was a Communist.
The question is how do people like Hayden and Trumbo reconcile the two opposites? It’s like they joined as it seemed the Socially Acceptable thing to do but were not really committed since they, and so many others like them, so enjoyed the “Perks” of the capitalist system. Which for the most part makes them total Hypocrites.
What about James Cagney and a bunch of Hollyweird Liberals that protested against the Congressional Hearings into he Hollyweird commies.
Hayden later testified as a friendly witness for HUAC.
