Same reason niggers do.

I'll give you a more accurate answer than simply "Whites are superior". It's rather simple an explanation too. In frontier lands the population is overwhelmingly male. Given the scarcity of White women, the native women are easy to score and marry. Miscegenation wasn't on their minds because life was difficult and short and these guys weren't thinking of anything beyond their immediate needs and desires. And these guys are not the alpha Chads we're talking about. These guys were the average Joes who probably weren't going to do well with the White women anyway. Getting with a feather indian was leaps and bounds better than never getting laid or having a wife. They fucked up, but it paved the way for many of you faggots with European and indian blood to be here today.

Women are hypergamous and genetically programmed to procreate and orient themselves towards males that can provide. As their cultures and civilizations were wiped out or subsumed, many feathered females instinctively knew their chances of survival and genetic legacy were far greater with Whites than their own. This phenomenon has played out time many times throughout human history.

Because white supremacy is real

It ties into their caste system which may not exist on paper anymore is very much real and their country has the largest amount of people in poverty on the planet who are considered 'untouchables'. Not b/c they're above the law.

but b/c they're viewed as diseased and disgusting. This is Indian (dot heads not the scalpers) empathy

Anyways skin lightening and bleaching products sell like crazy there

it's seen as status to be whiter. and much of their upper class would look more or less white if you changed their skin tone from all the fuckin the brits did...
