It's reductive, but not totally inaccurate. The Stoics hated the Epicureans, because the Epicureans preached withdrawal from politics and the quest for political (military) honors, whereas the Stoics made those one of the defining principles of the virtuous life. Stoicism was adapted to imperialism in a way Epicureanism was not. Same way Pauline/proto-orthodox Christianity won out over the diversity of early Christianity --- it was usable by the Roman Empire.

Maybe you should consider being more stoic about it.

Stoicism is a technology of control — inward control so the outward system can function. It’s the same structure as algorithmic behavior modification, as corporate “resilience” doctrine, as military discipline, as American hustle culture.

Maybe see the cup for what the cup is, not what you wish it to be for yourself to cope with reality.

Furthermore it is not “rude” to criticize something. And Aurelius would certainly call you out on that with a laugh.
