They retired Chadwick's character and damn near dedicated a movie to his memory.
You mean they used Chad's (a heterosexual black male) passing to sell tickets.
So you think them pulling a War Machine here - silently replacing one black actor with another - would have somehow been treating "black heterosexual males" as less disposable?
Your goofy ass literally watched a movie with 3 different Spider-Man's from three different continuity's in the same movie
Of course Black Panther should have been recasted and if the character was a cac that would have happened.
Meanwhile black main characters played by heterosexual black males get SHUT DOWN and put on ICE by Disney.
