Well, I've already explained exactly why it's a continuation of native American genocide and how race is 100% a driver for these organizations en masse, even though other races are also affected.

It's not a hyperfixation on race to acknowledge racial issues and address them.

I guessed you were from an area with colorblindness as it's main racism, I am as well. That's because you're in an area that is still colonizing land from Natives, so it's important to reduce their claims. One way to do this is to erase their heritage and ethnicity by forcing language, names, holidays, foods, etc that aren't part of their history. Suppressing claims of racism automatically is colorblindness and part of how colorblindness is racist.

Another form of racism placed onto Native Indian people is color-blind racism. This form of racism rationalizes “racial inequality as the outcome of nonracial dynamics” (Robertson 120). Color-blind racism takes the standards created by the dominant discourse and applies them to all ethnic groups, putting them on an even level plain field without recognizing historical or social context of each group. Therefore, according to color blind racism, the effects of casualties and stereotypical of Native Indians such as alcoholism, poverty, etc. is essentially their fault and they should be the ones to start change. However, these the casualties of Native Indian culture was changed by racial oppression implemented by the dominant discourse. Therefore, Native Indians cannot be the ones to change of societal perception when they were not the ones to implement it.

The pressure to assimilate and narrow the gaps in our proximity to Whiteness goes hand and hand with so-called “color blindness,” or claiming not to see race. At best, this ideology is misguided because it’s predicated on the false assumption that if we do not talk about or acknowledge race and racism, then these issues will go away. It should go without saying that this is asinine, yet so many well-meaning White people wear their alleged color blindness as a badge of honor.

At worst, it is a White supremacist tool used to intentionally gaslight BIPOC and give White people a justification for turning away from the experiences and voices of BIPOC. Color blindness requires BIPOC to “grin and bear” everyday instances of racism. We are expected to do this all in the name of making White people more comfortable with benefitting from their ancestors’ ill-gotten gains, as well as current inequalities. This is the “polite” brand of racism that prioritizes White supremacist notions of decorum, comfort, and acceptable forms of social expression over dismantling racism and alleviating the suffering that it causes.
