Cultural Appropriation is utter fascist bullshit. The idea behind is that it is “racist” to enjoy anything that isn’t of “your culture”.
In other words, by this SJW logic, we’re all racists for enjoying Studio Ghibli movies, or for eating Chinese Food. DAFAQ? It doesn’t make any sense. SJWs made this term up so they can bully artists and writers, to control what can and cannot be expressed. That is it.
I will say this, if you’re going to write about a culture outside your own, take time to research about a culture if you’re gonna write about it.
For example, compare Disney’s Peter Pan’s portrayal of Native Americans, vs say Pocahontas. One was goofy made up shit, one actually did some research. Also, concerning race relations, write your characters, all the characters as people first. Think of race/culture in terms of something like sports teams and or heck fandoms. At the core of everything we’re all just people. How we look, dress, talk like, believe, etc. that’s all external trappings. Nothing is sacred. Don’t worry about it.
