According to the American educator Herbert Kohl, writing about debates in New York in the late 1940s and early 1950s, "[t]he term 'politically correct' was used disparagingly to refer to someone whose loyalty to the CP line overrode compassion and led to bad politics.
Herbert Kohl's description of "politically correct" as a negative label applied to those prioritizing party loyalty over compassion is relevant to discussions about political correctness, its historical usage, and its potential for misuse.
