That's fine regarding paragraph 2, but its gross to tell an indigenous culture the evil spirit from their folklore actually isnt evil and that saying so is racist. Doing so as if thats actually a progressive take is particularly gross. Comparing said evil spirit to black people is also gross, that is an obviously faulty comparison.

You are not the author of their culture. They are. You can imagine this is a non canonical exploration of the idea of a wendigo just like the people who imagine fucking one, but it's an evil creature. It is their folklore that they have a ravenous hunger for human beings, and are explicitly evil.

Claiming to have the authority to negate a culture's own voice on aspects of their culture is a deeply disrespectful thing to do, please don't.
