McCarthyism began in 1947, with Truman demanding goverment employees be "screened for loyalty". They wanted to remove anyone who was a member of an "organization" they didn't like. It began with hearings, and then blacklists, and then arrests and prison sentences. It lasted until 1959. (https://en.wikipedia.org/wiki/McCarthyism)

This is the new McCarthyism. Do what the administration says, or you will be blacklisted, or worse.
