Dude you don't have to white knight for the douchey PhD guy. Saying shit like that, even if you are really super duper smart, is incredibly arrogant. People that say shit like, "I'm super smart and you're super dumb and I have a piece of paper to prove how super smart I am." Are gigantic douche bags. It ranks up there with, "I have a huge IQ." In levels of douche-dom. In fact, the more I think about it the more I think this is some shit that Trump would say. Just outrageously, fart smellingly, douchey.
So no I'm not gonna imagine the scenario where you somehow think I'm a 5th grader and you and PhD guy are the only super smart people on the entire internet. Not only is it a douchey thing to say, but also would make me a douche, and I really don't wanna be a douche.
