I think, if you were ok with a white woman (Scarlett Johansson) playing an Asian character (the Major) you are a racist. Also, if you had a problem with a black man (Idris Elba) playing a white character (the gunslinger) you are a racist. Wait... Something about that doesn't sound right.
Hollywood is too white. Bollywood is too ... No, that's not right either.
Maybe, people need to lighten the fuck up. Who cares if we got a black gunslinger, white Major, female Ghostbusters or a "diverse" version of star wars. The fact that all of those movies were mediocre at best is why they should have been panned. Not some prissy left or right wing agenda.
Can you guess how I feel about SJ playing a trans character? The answer would have been, is the movie good?
The only people who have a problem with Heimdall being black are comic book fans who don't think anything should be different. It is never about racism.
the same people that get upset if you made a black character white, wouldn't get upset about making a white character black. ---
