They also sidestep the fact that the lefties who were blacklisted really were commies. If there is a "behind the scenes" documentary about a movie from that era, or if a TCM host introduces the movie, they may refer to a writer or director being blacklisted after they were "accused of communist affiliations"; but they always fail to mention that most of these people were enthusiastic card-carrying members. If there is nothing wrong with being a commie, why do they always sweep that under the rug?
If the director had been successfully blacklisted, he wouldn’t have gotten work. People on the productions hired him using a pseudonym so that the Americans boycotting such productions would not know.
