Robert, there certainly are a number of similarities between Stoicism and Buddhism: https://massimopigliucci.medium.com/stoicism-and-buddhism-a-comparison-58d3e86587b

But I find nothing confusing about Stoicism at all. Hitler’s action are quite obviously not good for the human cosmopolis, since they imply the superiority of one group and even the extermination of another. I don’t see how anyone could possibly justify that on the basis of Stoicism.
