I was probably overcompensating, trying to be civil. Yes, imperialist/racist views of the 19th century used this narrative a lot. 20th century racism had a lot of pseudoarchaeology thrown into it too. The concept of "civilisation" especially. A lot of the actual theory is marxist though, a materialist narrative of the neolithic.
