Once again I have a Chunka Luta book recommendation: Indigenous Paleolithic by Paulette Steeves

Archeology as a discipline in the West functions as a Colonial tool to deny the history of Indigenous peoples. The biggest example is the "Clovis First Theory" (debunked) that posits all Indigenous peoples of the Americas descend from migrations across the Bering Strait during the last glacial maxim. Archeologists who made their careers on this study have bullied and physically harmed opponents to their hypothesis. US settlers over and over have destroyed archeological sites intentionally (and many unintentional as well) and this has been used to deny how long people have been living in the western continents. (Another example is the "genetic testing" and other racism that posits European settlers are "more indigenous" than Arabic-speaking Palestinians).

This is once again, a projection onto China what the Whites have been doing all over the world.

unlike the united states which relies on non-material religious justifications for its rule

As in the Chinese and sinicized cultures living there for last 2000 years? How about we search for some Euro artifacts this old in Americas?

in comparison to the US "might makes right" justification for its rule on american continent

But Xinjiang is part of China…

It doesn't make sense

They are making it sounds like they are unearthing ancient progenitor weapons to subjugate the population. Man, I knew I should have gone into archaeology.

Can anyone recommend any reading on China and the Xinjiang area or Uyghur nationalist movements?
