Lol you're telling white people to check their privilege, how about you do the fucking same. I'm Native American we have less rights and privilege than, Whites, Blacks, Asians, Hispanic. All of you have more privilege than NA's do. So really stop pinning on white people how easy they have it, you have it pretty damn easy yourself.
Privilege is something someone gains because of status symbols they're born with due to their population being a power population. Unless there is a historical, systematic institution of oppression perpetuated against Native Americans by Black Americans, then there's no privilege at play there. Our colonizer is the enemy here. Black people did not oppress Native Americans, so if you have an issue with the status of Native Americans, I suggest you take it up with the white supremacist power structure. Attacking black people for what white people have done is nothing more than anti-black bullshit, and you can blow it out your ass.
