Living in a cave": I don't remember the texts talking about a cave. Am I correct in assuming you use this as hyperbolic shorthand for your opposition to literal interpretations of lathe biosas "live unknown" and "Epicurus forbade being active in politics"?
Yes - exactly.
But I do see a general recommendation to not rock the boat, and I think this comes from Epicurus's own life experience.
i would rather put that "a general recommendation to be prudent in how you go about rocking the boat.". I think you are correct and Epicurus saw himself as a revolutionary , but knew that the deepest revolution has to be prepared for at a deep level - a position we face too today, I think.
Sorry to be short but I am driving....
In general I agree with your comments - what you perceive is there mostky due to ten years of fencing with Stoics on facebook who think that there is nothing interesting about Epicurus other than a twist-of-words take on asceticism. And on general they are quite unstoically assertive in how they advocate their position and ridicule the common sense approach you are taking.
