ELI5: Explain Like I'm 5

Rockism

Rockism is a way of thinking that believes only rock music is real music and that other types of music (like rap, pop, and even some other kinds of rock music) are not as special. People who believe in rockism think that only some kinds of rock music are “real” and they don’t like other kinds of music. It’s like thinking that only one kind of food is the best and that all other kinds are not as good.
