The conflation of Stoicism, an established and codified philosophy, with the more general idea of bog standard stoicism is precisely my criticism. The author is not using the term differently from me, they are using it incorrectly by conflating it with a more general, and more modern, term–a term without established codification, and vastly different connotations.
Which leads directly to the point I actually made–which you entirely ignored with your reply–that anyone who uses the terms interchangeably, conflates the two, or teaches one as the other fundamentally misunderstands the terms they’re using. Thus my statement that the author is laying the connotations of one term at the feet of another, different and distinct, term.
Stoicism (capitalized) and stoicism (the more general, more modern term) are not the same thing, which is why this article, in my opinion, misses the mark.
