When someone insults you are they responsible for how much you value their opinion? Are they responsible for how much you want to be accepted? Are they responsible for how many rejections you have had in the past?
But no this isn't particularly useful to actual humans who are still (easily) overwhelmed to madness with reactive pain, and the stoics compassion feels like that shown by the (non-hysterical) passengers in that one Airplane! scene [0].
(It occurs to me that expressing cruelty toward those suffering from hysterics is more than mere sadism; it may be a legitimate coping mechanism with their own fear. Focusing the mind on something, even hatefully, can save the hater from their own fear that the world is completely out-of-control.)
We are not robots. We are human. And while we cannot be automated, we survived due to our ability to adapt. Where we channel your attention, what we choose to focus on, and what we choose to value *is* something we have control over.
The idea that someone saying something to me and those words control me, my mind, and my world...that's silly.
Stoicism is about controlling what you have control over. Chief among this… is our thoughts.
Thoughts matter. How one thinks about things, events, situations that happen to us… matter.
Re-framing and interpreting how one thinks about what happened to us. Is important, for peace of mind.
Cognitive Behavior Therapy is an example of how one can apply stoicism.
Stoicism is about realising what you have control over and what you do not. It about acknowledging the agency you have no matter how little it may be.
Even if you have a tendency to be very reactive there is always something you can do to nullify or lessen the impact of an insult.
