The most effective way to indoctrinate people is to insinuate the desired ideas and attitudes into everyday discourse. Anticommunism pops up absolutely everywhere in a relentless drip, drip, drip of negative thoughts and images. Each drip may be small, but the result is a steady accumulation in the mind.
Here is another tiny example, this from the Netflix comedy series GLOW.
A minor character, who is supposed to be a Jewish refugee from the Soviet Union, is watching TV. Someone asks him what he is watching. He replies, in his Slavic accent, “In Soviet Union, TV watches you.”
Of course this is all nonsense. I know exactly where that “TV watches you” idea comes from: George Orwell’s novel 1984, where in fact the TVs are surveillance devices. Once again, an anticommunist fiction becomes a part of the universal standard story about communism.
