that is correct hope davidski read what you
say before r1a propaganda
Some people of European descent have a massive inferiority complex, partly because of the particular history of their area, and partly because the late arrival of "civilization" to European shores "offends" them.
I really do think even some academics subconsciously were influenced by these feelings. (Some, imo, had to be aware of the subtext. The history of the Journal of Indo-European Affairs makes for interesting reading.)
That's why, imo, the whole "Yamnaya Indo-European" saga was so wildly "off", with cultural practices of steppe nomads of the Iron Age attributed to people who lived two thousand years before and had much different practices. It's also why there was a conflict with the archaeology.
Of all the cultural "innovations" once attributed to the steppe groups, the only one left is the domestication of the horse. Everything else was borrowed either from "Old Europe" to their west or Maykop: the herding of domestic animals, the wheeled cart, metallurgy, even the kurgans. It took forever for the evidence to come out and be accepted, although if you ever read someone, anyone, besides David Anthony, particularly the Russians, the evidence was there already, although not as much of it as was later discovered.
It's the same with the growth of elites and elite burials. It happened elsewhere first.
You have no idea how long I was saying all of this before it became accepted even on pop gen boards. As I said, it was hard for certain Europeans to accept, indoctrinated as they were into the concept of the steppe ubermenschen. The Yamnaya people were in the right place at the right time to borrow technology from others, marry it to the domestication of the horse and a warlike mentality, and spread out to take over "greener pastures" when the steppe dried out. The Huns and Mongols did much the same thing thousands of years later. The civilized core falters, and the peripheral more mobile groups invade. It's happened over and over and may happen yet again.
