Purpose do squealer serve in the book; animal farm, how might society learn from this?

The best known of the porker pigs, Squealer has “very round cheeks, twinkling eyes, nimble movements, and a shrill voice.” He is also “a brilliant talker” who is talented in the art of argument. The other pigs say Squealer “could turn black into white” (35). Under Napoleon’s rule, Squealer acts as the liaison to the other animals. He lies to them, rewriting history and reading them encouraging, but false, statistics. Squealer is especially good at playing on the animals’ ignorance and gullibility. He represents the propaganda machine of a totalitarian government. Society might best learn by avoiding listening to loud and ignorant people.
