While the lyrics of "Polly" and "Rape Me" (don't see that on here though) aren't exactly the happiest lyrics they've ever penned, Kurt did specifically say on more than a few occasions that they were actually anti-rape songs. "Polly" is a beautiful-sounding song, but I guess we're just judging based solely on content. Also, I don't quite understand why you're trying to make a case <em>against</em> Nirvana. They had some nice-sounding and overall great songs. I mean, at least try to just be neutral. Oh wait, Conservapedia. Nevermind.
