Go ahead. There used to be a tv show called I Led 3 Lives. It was about a US agent who’d infiltrated a Communist cell operating in America. It was based on a real man’s experiences (and his book).
I’ve only seen a few episodes.
One had a commrade’s daughter spend the weekend with the agent’s family. The family knew what daddy did and weren’t supposed to let on. Well the commie kid pushed all sorts of PC talking points as the focus of all discussions of America history. I think this one was called Little Red Schoolhouse.
Another episode had farmers in an uproar at the government to suspend nuclear testing (at the proding of Soviet agents) because it was “affecting the climate” and ruining the growing seasoon. In the episode the USSR was really trying behind the scenes to catch up the US nuclear program and needed us to halt testing awhile...
These were from 1962. Kennedy era. Post McCarthey.
Also the things that people laughed about in the 1980s when they looked at Jack Webb as Rod Serling in Red Nightmare (a man wakes up to find his whole town has gone Commie) are coming to pass.
The “middle ground” in America has surged Left but we aren’t supposed to have noticed.
