Well, I hope you don’t mind me saying this, but you seem to me to just have answered your own question, insofar as your reply shows you’ve not really understood the concept of “cognitive distancing”, how the Stoics understood it, and why it’s so important in modern psychotherapy. You’ve overlooked points made in the article itself, such as that it’s not just that our feelings are subjective (as you say) but that they’re determined specifically by cognitions, which matters.
