Cops vs. Indians

Lol. After I wrote the story, I was all, "Fuck. Did I just reproduce the white supremacist narrative of civilization vs savage?" I mean, there's a limited number of plot elements available for the story.

The townspeople could fight:
a. savage tribe of post-apocalyptic humans
b. other town
c. themselves via civil war
d. animals
e. mutants
f. aliens
g. robots
But I wanted to give it a Fallout feel so I chose the (a). I think its possible to not reproduce that racist trope
