Yeah I really don't give a single shit who plays what character, or if that character is "supposed" to be a different gender/race/whatever. It used to be minorities would get these otherwise "white" roles and some people would make some noise but largely no one cared. I know I watched those shows/movies and never even gave it a second thought. Nowadays it seems the opposite is happening, people make a big deal when minorities get these roles because they love the idea of the person getting the role being black. Case in point? A few posts in the past dozen or so posts.
And this ties into the other situation we are now seeing where people demand minorities (race, gender, orientation, etc) be given more roles. Honestly why do people have to ruin everything?
