author seems to fundamentally misunderstand Stoicism
Or rather, is using the word “Stoicism” in a different way than you are. Like when research obviously shows a link between Christianity and intolerance and people come out in droves to say that true Christianity is about love instead of hate.
Yeah, sure, you learned a neater version of stoic values. What the author is referring to is a bit more generalized, a caricature but very real form of stoicism that some people preach, sometimes even without even calling it stoicism themselves.
