Answer:
The Red Scare was a period when people were afraid of ideas such as communism and anarchism.
Explanation:
Red Scare is a term referring to two periods of strong anti-communism in US history: the first going from 1917 to 1920, and the second associated with the Cold War, from 1947 to 1957.
Both stages of Red Scare were characterized by fear of the supposed influence of communists in American society. The first Red Scare was related to fear of growing anarchism and trade unions, the second concerned accusations of infiltration of the American government.
The result of the ubiquitous fear and suspicion characterizing the studied phenomenon were aggressive investigations and - especially in the first Red Scare- numerous arrests, sentences and deportations of people sympathetic to anarchists, communists and propagating ideology or political socialist movements.
