I’m willing to admit to being jumpy. I’m willing to say that I’m the type of person who might shriek and accidently spill his popcorn at a movie theatre. However, that’s not my problem.
As far as I see it, the base concept of the horror genre is Normal = Good Abnormal = Bad. In horror, the protagonists are just regular people. Yes, sometimes they’re douchebags, but they’re still the sorts that you’re supposed to root for to survive. The antagonist, however, is portrayed as the one person who is different. From a physical/mental deformity or disability, being associated with the supernatural, being born from or raised in an unusual circumstance, being from an unpopular ideological group, going through an unfortunate event, or losing someone precious to them. Even going so far as being unpopular.
Humans are naturally frightened by what they don’t understand. For some reason, they seem to enjoy being afraid. So, Hollywood and media like to capitalize on this form of entertainment through fear, and fetishize the archetype of the evil outsider. And even though it’s entertainment, people still subconsciously treat it as reality. Especially when real life horrific events happen. Do you know how many people said that because I’m autistic I might be a serial killer because they think we can’t feel compassion? Or that I might bring a gun into school or work place where I was bullied, just because someone else did it in a whole other state?
This isn’t to say that I condemn the concept of this form of media, but it can definitely be balanced out. Human society and history certainly contains plenty of examples of “Normal” or “Popular” people doing horrific things, or people who aren’t normal or popular experiencing fearful events. We can have a movie in high school where the cruel and apathetic popular kids decide to hunt down, torture, and kill the nerdy kids just for the fun of it. We can have a movie where a small group of Pagans are being stalked and murdered by a fanatical religious group.
Hell, I once tried to write a story of a detective sent to a small rural town that reports werewolf attacks. Then he finds out that the town hosts a chapter of the Klan, and they’re kidnapping minorities and killing them. So, the werewolves are actually a coven made up of other town members using witchcraft for the sole purpose to battle the klan and stop their killings. Because I like the idea of the abnormal/supernatural trying to do some form of good.
Human history is filled with potential for horror, but people seem to prefer demonizing the outcast. Even though it’s done for the purpose of amusement, lots of people can’t tell fact from fiction.
