A common critique of anarcho-primitivism and other anti-civ theory is that civilization and agriculture were practiced by indigenous people before colonization.

How can it be a legit critique? Even if indigenous people practiced agriculture before colonization?

Tangentially related, but small rant:

In some places indigenous people practiced agriculture, in other ones places they did not. In some places the hierarchy of indigenous groups was created by colonizers in other ones it existed before. Don't need to put all the different indigenous people all around the world under one one umbrella, pretending all of them have been lived free from oppression in a true harmony with the nature, unhierarchical societies without gender binaries and roles, without hierarchy-forming religions. Looks like some sort of fetishisation.
