all i'll say about that is the color of their skin has no bearing on their character. is jimmy olsen still a photographer? is perry white still an editor? do josie and the pussycats still sing? they do? then there isn't a problem, other than the possible impression you're giving by focusing solely on that as a negative. but that's your choice. people didn't love them because they were white, or if they did, they were loving them for all the wrong reasons. attitude. character. personality. i guess it's time to trot out the cliche "it's what's on the inside that counts" . . . but it's a cliche because it's true.
Well.... I have to disagree. The color of skin does matter. Are you saying that Blackthorn's adventures in Japan are not informed by his skin color and Western culture (Shogun). How about King's The Green Mile? What about How to Kill a Mockingbird? Obviously I've just laid out a few where race is a KEY issue in the conflict, but that isn't the only place where it matters. Skin color is a character defining feature. Whether we like it or not, ethnicity is a factor in sub-culture in this country (and most others). It informs. It is part of the experience. Can Jimmy Olsen be black? Sure. I've seen that in the Supergirl television series. In that case, his ethnicity has no bearing. There are characters in fiction for whom ethnicity and gender are irrelevant. You will never hear me make a peep in that case. There are, however, characters whose story is deeply affected by such choices. I am always going to be against casting choices which remove entire planks of defining interactions and characteristics.
