A Marvel Race Fiction For Today
I noticed in the original version of the TV 24, that the "bad guys" always started out as some group of "people of color" and as the season progressed it turned out they were just being manipulated by a more evil and more "cunning" group of white people. The writers had no idea their racism was showing. C.S. Lewis once pointed out that good and bad are corollaries of each other, inasmuch as while a bad horse can do more damage than a bad mouse, a good horse was of much more use that a good mouse. And a bad man could do more damage than a bad horse, a good man could do more good than a good horse. Power and propensities works both ways--for good or for bad. By acting as is non-white people could not be as evil as white people they were also making the claim that people of color could not be as good as white people--both equally absurd ideas.
I'd read a Sickle graphic novel. You're right, though - even in the old Luke Cage comics, all the supervillains were white guys. I think the only supervillain I can remember who wasn't was Fu Manchu, and I guess Our Moral Superiors don't want us to read about him because it's RAAAAACIST. Funny thing about those stories, though - the English "heroes" are the biggest bunch of dumb idiots you ever saw, constantly bumbling from one screwup to another and barely avoiding death thanks to Fu Manchu's slave girl who inexplicably falls in love with one of them.
