like the weird uncle who always says something unsettling, but yet always says something thought provoking, too. and, even the unsettling parts are thought-provoking. so, you just deal with it.
and, in a sense you define yourself against the parts you don't like. if there's a relating process in some of these songs, he's setting himself up as an adversary - something to flail against, an opponent. so, you relate with the antagonist, rather than the protagonist, even if it was at one time flipped. and, that goes back to singer as narrator, which is a more historical role.
