...so I happened to see Thor with a friend who is West Indian.
And every time I saw some internet fanboy bitching about Idris Elba as Heimdal, I thought about the way my friend's face lit up as she leaned over to me and said "There's black people in Asgard!"
She. Was. Thrilled.
Seriously, Certain White Folks. Let me break this down for you in small words, as a fellow white person.
1) It costs you nothing when a character who was historically white is recast as black. No-thing. From the Norse, "Not a damned thing." It costs you even less when a black character is played by a black actor. If you're too self-absorbed to notice that a character whose skin is described as brown is in fact a brown person... that's not anybody's problem but yours. Yes, we in America live in a society that defaults to white. Also male, cis, heterosexual. That doesn't mean you have to be an asshole.
2) It means the world to somebody who's used to being unrepresented to see somebody like them in a work of art.
3) Now imagine that that somebody who's used to being unrepresented is a twelve-year-old girl who is in the midst of forming her adult boundaries and identity. ...Means even more to her, you dig? You support that or you're an asshole. You don't have to be an asshole!
4) Idris Fucking Elba is ALWAYS A PLUS. Full stop.
5) Not merely racists. But racists with crappy reading comprehension.
6) As my friend hawkwing_lb says, "Bollocks to them."
