Whatever the insanity of foreign Communist regimes throughout the bloody 20 century, the point is that America was right in it's mid 20th century effort to uncover the communist infiltration into American society. HUAC only had the authority to subpoena witness and the Truman administration had no power to "blacklist" communist targets. Hollywood blacklisted it's own when the movie industry thought movie goers might not watch movies written by communists. The concept is open for debate but one thing is sure, the single loudmouth republican senator wasn't responsible for the communist purge. The media (that never saw a democrat they didn't like) protected the democrat party and president Truman from historic criticism when the communist threat dwindled. In retrospect you couldn't imagine that the media would be able to blame the era on a single republican senator but that was the power of the press (combined with Hollywood at the time.
