Why do we often get criticized or attacked when we don't agree with the majority?

Or conversely.

When we listen to the song that the majority listens to, then the minority starts bullying.

For example, there's an artist x who's very well-known and everyone listens to them, but I don't like them and I don't listen to them, and then I get criticized for it.

Or vice versa, when you listen to a singer that everyone else listens to, the minority who don't listen to them start lynching them.
