Here Mark Steyn points out that a liberal, Hollywood great has been vilified because he determined that stating who had been Communists with him in the 30's and were not owning up to it in the Hollywood of the 50's was a moral duty, not some cause for complaint. Both Bud Schulburg and Eli Kazan have been written out of the list of the right and good for stating, truthfully, that they were Communists and the other people were communists too. There is not one accusation that either man ever named a person who was not a Communist as a Communist. This is not McCarthyism, it is truth in labeling.
Further, there was no black list if you did not want to be on it. Nancy Reagan met Ronald Reagan precisely because she wanted to know how you got off the blacklist. There was a procedure, supported by Reagan and John Wayne and other of the Hollywood anti-communists to clear the names of non-communists or former communists. The one thing not allowed was to continue to be a secret Communist.
Basically, you could work for Jack Warner or Joe Stalin, but not both.
The Left hates this. Studio heads did not want their pictures being used by agents of the Soviet Union. The Soviet Union directed its adherents to cling to secrecy. A knock down drag out fight over control of both SAG, and the the west coast longshoreman's union fomented by Harry Bridges went on between free labor and the Communists. http://www.answers.com/topic/international-longshoremen-s-and-warehousemen-s-union

I'd bet dollars to donuts that's how Kazan and Schulberg came up with the longshoreman's analogy of On The Water Front.
In any event, since at least Woody Allen's "the Front" New Hollywood has preened and capered about how horrible the "blacklist" was. In fact, it was a reasonable request: if you want to work in this industry reaching millions of people we insist you break all ties with a murderous, atheist movement bent on the destruction of United States.
Oh yeah, also stop trying to kill John Wayne.
