This thread isn't going to end well.
Anyway...I think people are trying to make this about race when it isn't. To me, it's a perfectly valid statement to say "let's stick to the look of the comic book as closely as possible". For instance, a lot of fans might not want Spider-Man to be blond or freckled. That doesn't mean that anybody has anything against people with those traits. From that perspective, skin color is just another trait.
