I force myself to listen to crazy angry conservative and christian radio on and off for the same reason. If we can't embrace aspects of human personality that we find loathesome, I don't think we can love others, or ourselves.
Interestingly I feel like this article comes from a similar place as anger radio (which is, ironically, overwhelmingly money-motivated and exploitative).
I guess what I'm trying to say is that I don't see the value in otherizing media like this. It exists, it's part of our culture, and in one way or another, it's a part of us. Embrace it, engage with it, teach from it, but don't revile it.
