Sorry buddy, these are not the stereotypes you think they are.

Lots of different movies feature lots of white people. Zombie movies often feature minorities. Frankly, zombie movies have much more to say about modern life than other genres. If they focus on white people more, it’s typically to point out how we’re pretty fucked up right now without the zombies. It’s not racist to comment on race. But you have by no means established that Fallout made ghouls as racist stereotypes.

Tribes have always existed, in every people group. We have them now, everywhere. We grow up in them. We build them on our own. Only loners live outside them, and they aren’t healthy. Just because diverse people revert to older tech after an apocalypse and get referred to as “tribals” does not make it racist. Even if it was, it’s the fuckin apocalypse! I’m woke as fuck, but some people might possibly become a little shittier at the end of the world. They could be calling each other much worse things. Regardless, you have not established any connection to America’s reservations whatsoever. Nor frankly, have you demonstrated that you speak for Native Americans.
