"[insert random class here] are comically apolitical. They only care about their own [insert activity/property here]. The idea they all work together, as a class to prop up [contemporary social economic system here], is... not plausible"

Ok so that is the template now replace with the most comical examples you can think of

-Feudal lords/Castles/Feudalism

-Roman patricians/Villas/primitive accumulation(or slavery)

-Catholic Priests/Churches/Catholicism

So on, you're right its absolute dumbest shit but it also stems from the complete misunderstanding of what "politics" is as well, I mean what are the chances the random person on the street even knows the actual origin of the word? How many Americans think politics was invented in 1776 or even later?
