Musings of a failed Stoic. I don’t think Stoicism is the problem for you. It is good that you recognize that there are toxic people. Perhaps you would do well to avoid them. Nothing wrong with that, and I don’t see how that contradicts Stoic philosophy.
I have a similar problem. I try to follow Jesus’ philosophy, but it is really fricking hard to love Nazis. However, I am an INFP personality, so it often seems like almost everyone else is a Nazi! lol
I am trying to avoid toxic people, but when I can’t I am going to try to kill them with kindness. We will see how successful I am, though.
