Jesus Christ hanging from a misshapen breadstick.
I'm white.
White people have historically treated nonwhite people like costumes. Like animals. Like fictional characters. Like subhumans.
The vast majority of nonwhite people aren't OK with it. Look it up. Read opinions. Read historical accounts.
As a white person, when the majority of nonwhite people say they have a problem with something, I don't fucking get to say "so?"
You don't get to be outraged on behalf of polynesians.
And i'm guessing that if they do find it offensive, it's not going to be the skin colour, but rather the "cosplaying a god" part they find distasteful.
But probably not even that, i mean it's not like i lose my shit everytime an american dresses up as Thor for halloween. I mean i might slap him around a bit for sure and tell him that "Thor has red hair you idiot, and what the fuck is up with those dumb ass wings on your helmet!", but that's about the extent of my outrage in those cases. No big deal.
