Question

What lessons can be learned from the McCarthy era about what U.S. citizens need to protect in order to preserve the democratic political system and American way of life?

Answer 1

The U.S. citizens needed to for one protect their borders and defect/prison exchange spies Freedom of assembly was limited due to the fact of communist Americans and the U.S. government did not want them to meet. Also freedom of press and freedom of speech were limited due to american communists. The government put in the loyalty program to dismiss employees suspected of having ties to communism. The FBI disseminated damaging information on individuals to members of Congress to influence public opinion about the communist threat.
