But yeah this is actually pretty true. It also feels a lot more 'relevant' to reality than the xenophobia thing I heard before so yeah.

There was actually an interesting proposal on why people enjoy the concept of zombies so much, and the theory stated that it was because of an instinctive and deep-seated hatred of the 'outsider'. In appearance, zombies are similar enough to the living person so as not be hated as something inherently not human, but in behavior, they are always seen as the 'bad guy', because zombies eat living people and that's something that's bad, which is more rare than you'd think in media and in real life. The road to hell is paved with good intentions, and it shows, as no one does anything just because they want to be evil unless they're some kind of psychopath, while zombies are just bad guys who pose a threat to the living without any rhyme or reason. Because of these reasons, it's easy to enjoy zombie media because shunning the 'outsider' is something that people are pretty much hard-wired to do and would probably do all the time if conscience didn't stop them.
