“Cultural appropriation” has become a hot topic over the past few years and the misunderstanding of it has led to cultural segregation more than anything else. However, the concept of cultural appropriation is legit. Negatively borrowing from other cultures and exploiting them should be a concern.
Want examples of cultural appropriation? Blackface parties still happen on college campuses. When non-black fraternity members paint themselves black, grab their balls, and sing in a ghetto accent, that’s cultural appropriation. When a non-Indian person goes to a costume party, paints a red dot on their head, and wears a turban (which has a deep significance and has to be earned in Indian culture), that’s cultural appropriation.
