Some people get mad when a person wears something or eats something or uses a phrase from another person's culture.  This is called cultural appropriation.  I really don't see what the big deal is.  Thankfully, this Atlantic article agrees, saying essentially that culture is appropriation.  One group of people likes what this other group of people does, so now they adopt it into their culture.  That's how cultures work.  And probably more so now that we live in such a connected world.  We come into contact with other people's cultures all the time, so appropriating them is second nature.  Take it as a compliment:  I liked your food and clothes so much, I bought some for myself. #sociology
