Couple others I hate: "Applejack is a background pony". Joke or not, she's done alot of the show, and alot for nearly every character in the show. She's done more than Rarity, Fluttershy, and half the time Rainbowshit....how the hell is she a background pony? Not counting Hasbro's stupidity with ignoring her in some merch.
And Fluttershy...oh gawd...so what, she stopped one random dragon once...that doesn't mean her "stare" or whatever, is going to stop anything and everything they come across. People act like it's the ultimate weapon or something...when it really hasn't done squat since the cockatrice. Sure as hell didn't stop Sombra and Tirek...
And good old Dr. Whooves...serouosly...no. He may be based on one of the doctors, but he's not them. At most, he's just a workaholic scientist.
