Eminem - No Apologies Lyrics Meaning

He's talking how he's getting all this bad press for supposedly being this evil person, but it has all been blown way out of proportion and does not reflect the person he really is deep down inside. That is, he is a wounded, depressed and kind of tortured soul who found rap as an outlet for all his emotional pain. I really don't think it sounds much like a "fight song." This song sounds like an emotionally broken Eminem who's on the verge of a total break down. It's one of the saddest songs he's done and kind of difficult to listen to.
