Cultural appropriation doesn't equal racism.. Racism is belief that one race is superior. Using concept from another culture cause you think it's cool is not racist. Ofc you can misuse that concept, even in a way that is offensive and then dialogue might be best. But in terms of cultural appropriation- or borrowing which word I like better, if it's not harmful to said culture it shouldn't be issue.
Good example is different food cultures. Is non-asian chef who makes and sells sushi racist? What about non-italian pizzerias, for example turkish kebab pizzerias my country is full of? I think most are perfectly ok when chef studies another country's cuisine, starts selling it or maybe even alters it- lot of cuisines we associate as products of certain country have actually been inspired by something else from other culture. Why is inspiration from other cultures ok and good thing what comes to food items, but not ok what comes to at least non-religious clothing/items..
Dreamcatcher is not using dreamcatchers in the way that would mock native americans nor they are causing direct harm by using the name.
This cultural appropriation stuff is going too far, now they are even discussing changin name of Geisha chocolate bars in my country that had been around since 60s and just cause some white person had issue with the name. No japanese has had issues with it. It's getting so annoying with these folks.
