His 1.2 GPA shining through again. Most kids around the world (or at least the Western world) learn about Thermopylae in primary school history class and they of course learn that the Greeks lost, which led to Persians conquering Greek territory, the Greeks then won at Salamis and launched a counterattack to reconquer parts of Greece that were conquered after Thermopylae. The three big battles that are focused on in the Greco-Persian wars are Marathon, Thermopylae and Salamis.
Because Patty Cheesesteak barely passed history and because he's a narcissist, he projects his ignorance about the Greco-Persian wars onto everyone else despite the fact that he'd get schooled on it by any 5th grader around the world.
