To be honest, I'm not sure I really feel like debating cultural appropriation right now, especially if you read that article and your main focus is the feelings of white people. But if that's one of the first things you've read on the subject, I would really suggest doing some more independent research because there are a lot of resources out there. I've spent a lot of time lately trying explain these kinds of concepts to people and why they're harmful, and I'm just kind of mentally exhausted by the number of people who aren't even willing to try to understand it. Frankly, I'm tired.
