Most societies have a time limit on when ‘grave robbing’ becomes archeology. When a cemetery has been abandoned by all who have loved ones buried in it, and it’s overgrown and is indistinguishable from surrounding terrain, it generally becomes open for historical investigation. This is particularly true when there is no historical record of it being there at all. it seems to me that societies that have no written language, and no history other than oral, have no right to pretend that their history cannot be investigated forever.
The goal is not a history as you & I understand history. The goal is to remove all evidence that contradicts the idea that activists want portrayed. With no artifacts and no written record, a complete golden age history can be created out of thin air. Spoiled only by the arrival of the West!
