Remember back in the day when writing songs about bisexuality was the thing to do? You don't? That's probably because it never was. But Ani DiFranco wrote a great one here, "In or Out":
And Ani, in her own words for About.com:
I've been looking at these political crises for myself in a sort of holistic way, and what I keep coming back to is patriarchy. I just don't, from what I understand about the world, peace is not possible without balance. And patriarchy is inherently imbalanced. I don't think there's any such thing as peace within patriarchy. I think men are great, they have all kinds of awesome ideas about the individual and individual rights and this is very useful stuff for things like Democracy. But individualism leads to hierarchy, which leads to aggression; so I think just the masculine sensibility is not enough to guide us to peace.
