What did Kazan mean by secrecy serves the communists?

Elia Kazan's statement that "secrecy serves the communists" refers to the idea that the covert nature of communist operations and ideology allows them to thrive in the shadows, making it difficult for democratic societies to confront or understand their tactics. He believed that the lack of transparency within communist organizations fosters distrust and undermines effective opposition. By exposing communist activities, Kazan argued that individuals and societies could better defend themselves against their influence and ideology. Ultimately, he emphasized the importance of transparency and open discourse in combating totalitarianism.
