Not sure what's greater in this thread, the racism or whining.
Who the **** cares if a comic-character's standard "race" is changed when 99% of the time the character's "race" is irrelevant to their story. I can understand if a character like the Red Skull was cast as Black or Asian or any non-white, since being "Aryan" is an intrinsic part of the charater.
eg People whining over the possibility of Spider-Man going black, when it doesn't matter. Peter Parker is an awkward nerdy kid, his "white" skin is next to irrelevant to his backstory
eg Does a black Johnny Storm matter when they added the change of "adopted" to his backstory? No, it does not.
eg People crying over a black Heimdall, when he's Asgardian (ie an alien for all intents) and not an actual Scandinavian
