Why are people not that open-minded?

I really want to know: what's wrong with listening to BTS? I know the first thoughts are like They look the same or they are chinese/ Japanese girls wearing makeup. We've all been through this but through their hard work they achieved so many things. Tell me pls why people who doesn't listen to them are so inhuman? Why can't people see that performing is art and music is art? It doesn't matter what you are listening to but music is healing and there is no barricade to understand music. It's about emotions and Living life. But because of their nationality so many people are so racist.
What's the actual probleme behind this?
