The ultimate success of a black man is to do what a white man does, as seen in Captain America: Sentinel of Liberty #8.
I’m not trying to pick on Rick Remender for having Sam Wilson become Captain America, but some things need to be said. I don’t want to go so far as to say that only a white writer would think to have Sam Wilson become Captain America, because that’s not the case. I do, however, think that only a writer who isn’t trying hard enough would come up with that already-been-done story. More important, I think only a writer caught up in existing racial ideologies would think it is a good idea that a black man assumes the identity of a white man, as if that is the pinnacle of identity.
