Second Red Scare.

Explanation:

The McCarran Act is a law that refers to the practice of accusing someone of subversion or betrayal. The term has its origins in the period of the History of the United States known as second red threat, which lasted from 1950 to 1957 and was characterized by a marked political repression to the communists, as well as by a campaign of fear to their influence in the American institutions and the espionage by agents of the Soviet Union. It has also been used to judge reckless and unsubstantiated accusations, as well as demagogic attacks on the character or sense of patriotism of political opponents.
