I myself am a fan of Peterson and enjoyed reading 12 Rules. Having said that, I also consider myself a Stoic.
One of the issues I encounter when people criticize Peterson is that the thesis statement is usually less important than taking a chance to get in punches. In other words, it becomes clear that they have little issue with the substance of Peterson’s ideas and more with Peterson as an individual, which then they parade as intellectual disagreement.
This piece did not suffer from that. You identify a problem (Peterson being considered a Stoic), focus on an issue (anger), and give examples of Peterson’s views on it, while explaining the Stoic position on it. It follows the “plain-spoken” way of discussing an issue to a tee.
