Long post; general gist: This is fucking ridiculous. CAUTION! Oskamunda uses the N-word!
First, let's point out what the article points out rather quickly and efficiently. The Aesir and Vanir of Marvel are aliens, not Gods. Something tells me that aliens capable of space travel [and therefore the astronomical resource management that entails--pun intended] would give two shits about the color of someone's skin. Something tells me that they don't even give two shits whether a species is mammalian or reptilian.
Second, even if they were Gods, there is no historical accounting of what they believed about those of different races or creeds. The Norse were known to absorb anything that was of use to them: armor, technologies, land, weapons, culture, deities, and most of all, people. If Heimdall wants to inhabit a black dude, there's probably a reason for it.
Thirdly, just because Wagner was a little fucked in the brainpan, doesn't mean that there is any connection to the Nordic ancestry of Europe and white supremacy. Just because he wrote about Reichs in his operas doesn't mean there actually was one. And just because someone wants to believe that they are better than someone else based on melanin content of the flesh, doesn't mean their cause is granted any legitimacy because some fuckwit wrote some pedantic, self-important music about it 200 years ago. [Incidentally, we don't actually know if Wagner was supremest; he didn't think much of Jewish music, as it wasn't "connected to the German spirit," but that doesn't necessarily mean he would have been one of the ones running Auschwitz, now, does it?]
Fourthly, W T F. Only in America can someone actually cause a stir about this. Mark these words of mine carefully, lest there be some alchemic application of personal opinion that changes what I am saying into something else. There is only one type of group that should be disallowed protection from the first amendment: Supremacist Groups. Why? Not moral outrage, not civil propriety, nothing like that. Philosophically, one should not be able to use a charter of protections to actively speak out against that very charter of protections. With the 4th, 5th, 9th, 13th, and 19th amendments to the constitution, every citizen of the US is protected from discrimination of all kinds. Forming a supremacist group, whether it be based on race, religion, culture, sex, or nation of origin, is basically taking a big fat shit on the constitution. Women, equal? Fuck that amendment. Niggers, free? Fuck that amendment. [oh, boy, I can see the complaints for using that word already, even though it was used to depict the ignorance of those who use it hatefully and to insult them] Spics, allowed to cross the border and become citizens here? Fuck that amendment. Jews, allowed to own property and not have it taken away from them unjustly? Fuck that amendment. Crackers, allowed to thrive and spew their bile and vitriol as far and wide as they can and be funded by private investments that also fund gears of government without transparency and further perpetuate injustice in all civil and economic spheres and refuse history to progress? Hallelujah for that amendment!
Bullshit. Chauvinists, misandrists, misogynists, racists, discriminators of all kinds allowed to thumb their nose at a constitution of rights meant to protect people rather than empower bigots, while simultaneously using that same constitution of rights to defend themselves and their ability to tear down liberties extended to people within the same document? Fuck that amendment.
And fuck those ignorant whip crackers, while we're at it. It's a goddamned superhero movie about aliens, not a historical accounting of your divine imperative to kill everybody with a bigger cock than you, you racist pieces of shit.
EDITED to add content:
Oh, yeah, and what would be the problem if a white guy played an African God? There's more than one in the Panoplia of Saharan deities that were albino...and one would think that the FIRST impression of a white man sailing across an ocean [not a river, an ocean] might conjure ideas of godhood. I suppose it would depend on the context.
