Fascinating post.
The manifesto (because that's what it is) is a study in contradictions. The blatantly racist language and, yes, tone are unmistakable. This is, I believe, what Charles Manson was aiming for with his "helter skelter."
Ironic, too, since a staggering amount of the Philly government is of the "African" persuasion.
I have to wonder, though, as proud as these people (the ones behind this manifesto) are of Africa, how many would emigrate there if given the chance? I don't mean the cliched "ship 'em out" type of rhetoric but rather the "forty acres and a mule" type of manifest destiny offer that inspired the American move westward. My guess is that not many would go to Africa regardless of how financially enticing the offer was. My guess is that the African "nostalgia" is pure BS and that the real love affair here is with a couple of dead white guys: Lenin and Marx.
