Nothing you're saying is wrong, really, but I thought I'd add some detail to it just cuz.
Here in flyover country a lot of us are an eighth or more of whatever the local strain was/is. I'm 1/16 Osage and 2/16 Ioway, so 3/16 total. Now that doesn't sound like much, until you think about the math and realize that's like a hair away from a quarter "native". I literally qualified for special student loans despite being a pale, blue eyed dude. And unless you're familiar with the bone structure you'd never know just looking at me cuz if you're less than half native your coloration starts looking real white real fast. I know a guy who's more than 2/3rds Osage but you'd never guess it cause he's fucking ginger and burns like a bitch in the sun. Why? The other 1/3rd is straight up Welsh. Injun genes ain't strong when it comes to color.
Hilariously enough, we all think of ourselves as full-on white, even the half or more ones that actually look the part of "natives" in terms of complexion. If you try and tell us we're not you're liable to get your ass beat, too. I used to date a girl that looked like straight up Pocahontas and if you tried to tell her she wasn't white she'd attack you, especially if you meant it in a """good""" way. Reservations are just for welfare, cheap cigarettes, gambling and drug cooking (they have their own police and other cops aren't allowed in, at least not the local brand of cops, feds are allowed in I'm sure.)
