So much of the bitterness that the term 'McCarthyism' evokes refers to the probe begun in New Jersey in the summer of 1953 - both in the laboratories of Fort Monmouth and in the surrounding communities of Red Bank and Belmar, where some of the best scientists and engineers in America worked.
The author of McCarthyism was given the distinction of addressing the Republican National Convention. This strikes terror in the hearts of honest men.
McCarthyism and Trumpism are very different. They stand for very different things, but the technique of the big lie, smearing and telling lies, you know, McCarthy was doing that. At the time, the media, Democrats, and Republicans were all paralyzed - not all, but most of them were paralyzed. They didn't know how to deal with this.
McCarthyism is Americanism with its sleeves rolled.
As is well known, 'McCarthyism' was an alleged focus of political evil in the 1950s: Accusations of Communist taint, without factual basis; bogus lists of supposed Communists who never existed; failure in the end to produce even one provable Communist or Soviet agent, despite his myriad charges of subversion.
