The Quileutes are the only non white people who are supposed to be the good guys, and they are not as good as the perfect, universally pale, vampires. For example, it takes several werewolves to take on one vampire.
Bella is supposedly safer with the perfectly-controlled vampires than with the unstable werewolves. The werewolves are the ones with the irrational prejudices against the perfect, fair-minded Cullens. The Quileutes turn into animals, while the Meyerpires just get superpowers as they are. The Native Americans are portrayed as poor: Jacob has a tiny house, with peeling paint, that looks like a barn; Jacob fursplodes at Paul, wrecking his shoes, and someone comments that that's the last pair he can afford. When Paul is at his house, Jacob freaks, because Paul is eating all of the food and they can't afford to feed him. Meanwhile the Cullens honeymoon on their private island, live in their giant white mansion, and give the werewolves their old clothes.
Admittedly, many Native Americans living on reservations are actually poor.
The Quileutes, unlike the vampires, run around half-naked, are prone to violent, disfiguring rages, and, oh yeah, wasn't it Jacob who forced Bella to kiss him? STEREOTYPES! The werewolves show all the stereotypes about "wild" and "savage" Native Americans to be true. The fact that they literally transform into animals doesn't help. Any Native American who has read the books would be offended by such close-minded ideals.
I know I was.
The Amazingly Purrrrfect Cullens Edit
The Cullens are shown as good, noble vampires, who have all gone through some sort of strife. Their control is remarkable; they have only met one other coven of "vegetarians" like them. The werewolves also need to exercise extraordinary self-control, as they are prone to fursploding if they get too heated. Many of the werewolves, particularly Leah Clearwater, have gone through struggles or are suffering now, but they are not treated as sympathetically as the Cullens. The Cullens do not seem to recognize that they have many of the same troubles. This may be used to illustrate the futility of their feud, but the vampires seem to be the ones to be "reasonable" here, and this is dissonant with Carlisle's supposed ability of "compassion".
The Romanian CovenEdit
Smeyer needed a Dracula stereotype. So she added it. 'Nuff said.
Teh Scaeri Villains Edit
Further adding to the unfortunate implications of the books' good consisting of mostly white people (with other races a bit uncomfortably seen as less controlled) is the fact that a number of villains seen throughout the series are non-white or portrayed as such in the movie version. Don't even get us started on Laurent. This may be lessened by the fact that most other vampires are controlled by thirst and greed, but it is still uncomfortable. The fact that vampires supposedly lose their pigmentation does not help, as their features plainly remain and set them apart. Jasper was bitten by a vampire named Maria; she is described as having clear Mexican features. Her portrayal is as a ruthless but skilled trainer who wars with the others.
One thinks it would be hard to function as a non-white vampire with pale pigmentation due to the risks of standing out or looking odd.
It is also revealed in Midnight Sun that Bella's would-be rapist had a Hispanic name.
Differences in Races From The Books Edit
The implications are partially remedied by the appearance of non-white actors in the the film adaptation, but these characters are seen as pathetic or unworthy. They barely get any characterization throughout the book, such as Eric Yorkie and Tyler Crowley, who exist only as partial friends to Bella. Further contributing to the racist implications is the fact that Eric has been made into the nerdy Asian stereotype. This is not remarkable in media, and even in real life, but the unfortunate implications remain.
Furthering this is the fact that in the movie version, Laurent adopts a rather Jamaican accent, and is portrayed by a black actor, and while he is not completely evil, his actions aren't seen as good by the protagonists. He is also the only vampire with any racial diversity to be killed (Yeah, because that isn't racist at all *sarca...oh hell you know by now*). The only racial diversity exists within the villains.
To be fair to Meyer, however, she probably had relatively little input in the casting decisions.
