> The common modern idea that Stoicism is merely about emotional repression and a totally "unemotional" stance is quite a misconception.

Honestly, I blame Mr. Spock. Another thought I've been chewing on is emotional repression from a certain crowd of people who grew up as socially isolated nerds and / or autists that identified strongly with what they perceived as hyper rational characters like Spock. Sprinkle in high technology and the fact that these characters succeed at things nerds love and you get hero worship and emulation. Then add in all the masculine marketing we get from "stoic" characters like the dude from Drive to get another layer to the equation.
