I don't think anyone will support an original black "mainstream" character. I know I won't.
Maybe they should establish a separate league for all the negro superheroes. I'm not saying kick them ALL off. One would be okay. (Doesn't Hollywood have some kind of law that says every movie has to have at least one black in it?) I just think they're going overboard with all this diversity stuff. I mean, how many comics do minorities read anyway?
