Why do fans of stars always quarrel?

Everyone likes different things. Those fans who hack others are usually self-blacked, but they are all blacked out. There is also a kind of sunspot, that is, deliberately hacking others, verbally saying which star you like, but actually not liking that star, just trying to provoke fans of two stars to pinch each other. So when you see those fans who are black, you should either ignore them or "hehe", and ignore those fans who have no quality and love black.
