Why do people fight about music? Because beauty and art is based almost solely on opinion. People have, sometimes, completely different ones. Thus, one person feels compelled to say something “negative” where they shouldn’t. Another person’s opinion is probably very strong for this music, so they feel as if they should correct them, or maybe even defend the music, or their own thoughts. Music is theoretically a reasonable thing to argue about, but it is very annoying and unnecessary.
