Propaganda Chapter 4 - The Psychology of Public Relations

"But when the example of the leader is not at hand and the herd must think for itself, it does so by means of cliches, pat words or images which stand for a whole group of ideas or experiences. Not many years ago, it was only necessary to tag a political candidate with the word "interests" to stampede millions of people into voting against him, because anything associated with "the interests" seemed necessarily corrupt. Recently the word Bolshevik has performed a similar service for persons who wished to frighten the public away from a line of action."

Good thing this doesn't happen in modern times. That would be DEPLORABLE and WOKE.
