It's a SPOOF...not a serious movie...maybe the issue is that Natives have been through enough, and maybe they should be exempt from things everyone else isn't exempt from....Like spoof of culture, but again...that's the point of a spoof.
Have you heard of minstrel shows or Polish jokes? Cloaking your prejudice in "humor" doesn't excuse or justify the prejudice.
The point of "spoofing" a culture is usually to denigrate and belittle it. That's why ethnic "spoofs" are usually prejudicial. You can spoof a culture properly--Woody Allen has done it--but most non-Indians aren't smart enough to avoid the usual mistakes and stereotypes.
In fact, mainstream movies aren't spoofing any minority these days. Studios have realized that such spoofs usually end up racist or bigoted. In the rare instances when they try such a "spoof," the critics savage them.
Vampire Sucks spoofs races equally?
If Vampire Sucks makes fun of white people as a whole, then you might have a point. But the only ethnic group it makes fun of is Indians.
There are plenty of white people in the Twilight Saga. Why didn't the producers make fun of the entire white race if their outlook was evenhanded?
What you've apparently missed is that Vampires Suck is "spoofing" the Quileute tribe's religion. It's as if the movie "spoofed" the Navajo's Changing Woman by showing a woman changing a baby's diapers and calling that sacred. Or "spoofed" a Ghost Dance by showing Casper the Friendly Ghost dancing around a campfire.
Catholics believe you're eating the body of Christ when you consume a wafer at Mass. Would it be okay to spoof them by showing cannibals gnawing on Jesus's arms and legs? Why not, if spoofing "everything" justifies cultural or religious "humor"?
The Quileute people honor wolves in their stories and ceremonies. The "Indians" in Vampire Sucks turn into Chihuahuas. The Quileute already have mixed feelings about Twilight's bastardization of their religion. What makes you think they'll appreciate the Chihuahua version better than the werewolf version?
