Wow. That's extremely immature.
I admit I sometimes really hate bands. But I don't disrespect them, I usually have some reason about their kind of music. But I do respect what they do, they are probably amazing at it. It's just not my favorite kind of music sometimes.
If you don't like paramores music,
don't listen to them.
What do they think that they are gonna stop playing amazing music because some people hate their music? Paramore knew coming into this business that some people would hate them, and some people would love them.
