I think it was more along the lines of "contempt for anyone who, when asked to write code to do something difficult that they're unfamiliar with, chooses to write very, very bad code instead of learning the bare minimum needed to do a passable if amateurish job".

Intolerance for egregious unprofessionalism and incompetence is not exactly something our field suffers due to an excess of.
