Elia Kazan was looked down upon ( and I’m being nice ) because he was former Communist and member of Communist Party USA, who testified in 1952 in front of the so-called House Un-American Activities Committee, for outing other Communists and Socialists who worked in Hollywood. And because of this Kazan was able to continue his brilliant Hollywood career as a direct or, producer, and writer. And as a result his colleagues in Hollywood refused to honor his great works because the Socialist-Left in Hollywood saw him as a traitor. Even though no one will even attempt to argue that Elia Kazan wasn’t a great writer, director, and producer.
So Elia Kazan had two feet kicking him in the rear during is career. One foot because the corporate establishment kicking him simply for being a Communist and kicking him simply because of his personal politics and beliefs. The other foot the Socialist-Left. Actors, directors, producers, writers, the employees in Hollywood, kicking Kazan because he came out as a Communist, which is like admitting to being a rapist or murderer, to the Fascist-Right in America.
We have a guaranteed right to free speech in America which of course covers politics but other aspects of what we think and what we have to say, with only a few exceptions dealing with libel, inciting violence, and harassment. ( Not offensive speech ) So unless you’re working for foreign government to try to hurt the United States, or involved in terrorist activities to advance your politics, you have a right to believe what you believe. Even if it offends tight asses on the Far-Right who have their own limited view of what it means to be an American. Or tight asses on the Far-Left who believe anything that is critical about anyone who is not an Anglo-Saxon Protestant straight male, should be censored.
To paraphrase Ronald Reagan. There’s nothing dangerous about one’s political beliefs and thoughts. People have a right to believe what they believe. America is so strong as a liberal democracy that we tolerate people who believe America is some racist evil empire. Which is what Communists and perhaps Democratic Socialists even, tend to believe. And we can tolerate people who believe non-European-Americans and even non-Anglo-Saxon Protestants, are basically animals not deserving of the same constitutional rights as the English-Protestants who came to America in the 16 and 1700s. Doesn’t mean fringe thinking in America shouldn’t be looked down upon and people who act on those fringe beliefs though violence shouldn’t be monitored and punished. But Americans shouldn’t be denied access in America and be blacklisted simply because of their personal politics.
