Any "Noble" Nirvana Songs?

I got in an argument with my dad, because he thought that the Nirvana song “Rape Me” was about a guy being like, “woo, rape is cool!”…Or something like that. I finally got fed up with my dad being so confused as to the meaning of the song that I googled it and informed him that “Rape Me” is an anti-rape song. So then he asked me if there were any other songs like that by Nirvana, ahem, “noble songs”. Meaning, I assume, songs that aren’t about drugs and aren’t angry…Bah, I dunno. Issue songs. I’m kind of a new Nirvana fan, so some help on this world be nice.
