If someone thinks Nirvana are better than The Melvins, thats pretty much their personal opinion, same goes for someone who believes vice versa, but being abrasive about it either way makes that band look bad, it makes people think "are all Melvins fans f*cking assh*les like these guys?", it dosen't help anything, it dosen't prove your point and it just makes you all look like douchebags, not that personal opinions can't be completely biased, and in this case Raine is likely very biased, but it's still her opinion.
