Hey, that's a great essay prompt.  It often happens that when threatened by some threat to our way of life in a democracy, we respond in very undemocratic ways.  During the McCarthy years, people's privacy was invaded as accusations about communists and communist sympathizers were aimed at all sorts of people.  Many people in the Hollywood film industry were targeted during that time, for instance.  But defenders of freedom (including film and television people) fought back against that.  We must always adhere to our primary aims as a society -- the rights and liberties of each individual.  We don't want to get into "witch hunts" where we suspect our neighbors of evil for no good reason.

Speaking of "witch hunts," the playwright Arthur Miller wrote a really powerful play in 1953, during the Cold War, which focused on the Salem witch trials. He was making the point that what was happening in the McCarthy era (hunting for communists) was another manifestation of the witch-burning craze that had happened at a previous time in history.
