Eminem was...bullied?

Eminem has revealed that he was bullied pretty badly in grade school and is now speaking out against bullying in an effort to combat the trend of suicides resulting from anti-gay bullying in schools.  Does this sound a bit off to you, because it sounds off to me.  A guy who uses the word "faggot" in nearly all his songs?  A guy who, I mean, let's be honest, does nothing but bully in a lot of his songs?  Maybe he's turning over a new leaf.  Or, maybe sales for is new album aren't quite what he was hoping for and he's trying to boost his image.  Regardless, I am glad to see more and more celebrities speaking out against bullying, but, I'm a bit suspicious about this specific celebrity.
