Once Draco was old enough to read for himself, he saw that the story was written differently than he had been told as a child. His father blamed blood traitors for making the story politically correct, and explained that the story was about putting your own selfish needs aside and helping protect and preserve Pureblood society, even from itself. He fed me years of lies to make me afraid of muggles, while inflating the importance of blood purity. Draco recognized that muggles were actually good people and had been innovative since they couldn't rely on magic, and was glad Hermione's parents were here.
