What did the United States do to counter the fear of the spread of communism in the 1920s?

Actions taken by US to counter the fear of the spread of communism in the 1920s:

The U. S. constitution provides for rights same as freedom of speech, press freedom and religious liberty. These and many other individual rights are protected by the Declaration of Fundamental rights. But not all the privileges in the constitution have always been upheld by the nation.

The Civil War prompted President Abraham Lincoln to take drastic measures to prevent the publication of war reports by newspapers. Yet Senator Joseph McCarthy, during the 1950s, threatened innocent citizens with becoming communists and turncoats.

1919 and 1920 were among the most severe government restrictions on personal rights. Occasionally, some government officials have taken illegal actions against employees, immigrants and others.
