As far as your very valid points of the white guy selfishly ruining the black guys life.. this movie came out 36 years ago, so there’s that working against it. But doesn’t it kinda ring true? Ever heard of white people showing up to black protests, trying to support but end up instigating violence? What about in Django, the German guy selfishly takes action putting Django and his wife in an unnecessarily dangerous situation because he just doesn’t consider the black man’s experience enough.
