You ever see Men in Black? There's a point, real close to the beginning, where the secret alien cop is talking to the NYPD cop that just saw an alien flip the fuck out and cause trouble. Aliens aren't public knowledge there like they are in our versions of the world. The NYPD guy asks him why they keep it a secret and says that people could handle aliens being real. Here's what the tired old alien cop says back:
"A person is smart. People are dumb, panicky dangerous animals and you know it. Fifteen hundred years ago everybody knew the Earth was the center of the universe. Five hundred years ago, everybody knew the Earth was flat, and fifteen minutes ago, you knew that humans were alone on this planet. Imagine what you'll know tomorrow."
My dad was a superhero. He was also a single dad, so sometimes I'd stay at the Avengers mansion when only a couple of them were going off on a mission, other times Thor or Hercules or Beta Ray Bill would just come hang out. I saw some shit. Aliens, resurrections, gods, monsters, robots, and even weirder.
And outside those walls, people are still spray-painting "mutie freak" on everything. People are idiots. They want a world where the round peg goes into the round hole and the square peg goes into the square hole and nothing ever strays from that happy little worldview. Being idiots is how they stay sane. Except sometimes I wonder which of us are really the idiots. The sheep, or the costumed shepherds that die for them.
