Cultural elitism is when someone thinks they are better than someone else because of their culture. It could mean something like a person from one country thinking they are better than a person from another country, or it could mean someone from a certain background or religion thinking they are better than someone from a different background or religion. It can also happen if someone only likes certain types of music or fashion, and treats people who like different things with disrespect. Cultural elitism is bad because it doesn't respect other cultures and backgrounds, and it can lead to people not getting along with each other because of their differences.
