Thaddeus Howze, I think your friends are right. It would not be logically right to expect that any white writer — with his ingrained sense of superiority about his race — would make a superhero out of a black character. The only practical way you can beat the trend is create a black legend yourself. And I think there are many talented black writers and creators around.
But I would like you to tone down your angst, though justified, against the Whites. It shows you in poor light.
