I've even seen this one pop up from time to time among our own. The idea that the first patriarchal society to step foot in Europe were the indo Europeans is almost, beyond question, a fat fucking lie.
The dominant group in Europe prior to them were the early european farmers. Who shared their blood with Mesopotamian people (as in, they were already closely related to them, and apart from migrating into Europe, they also migrated in significant quantities into the levant). Name a single matriarchal Mesopotamian civilization, and we are supposed to believe that their brothers were somehow matriarchal? Okay. Sounds jewish.
The people before them were the western hunter gatherers. Who probably weren't matriarchal either, because most non-niggers never have been, although they never achieved enough for it to matter. So it's trivial.
What's the goal of this psyop though? It's two pronged. One prong is to make normies think that patriarchy is evil and that it was forced upon the peaceful hippie matriarchal ancient Europeans by insane blood drinking asiatic invaders. The second prong is to make right wingers believe that half or more of their dna is made up of the blood useless pushover faggots, when in reality half of your blood is made up of the first builders of civilization in human history and its something to take pride in. Jews don't want you to, because they've never built anything.
No, they weren't as tall and strong, but they were objectively better civilization builders. And, given that they were far closer genetically to the yamnaya than anyone likes to admit, they probably could have been taller and stronger than they were if they had the yamnaya diet.
The synthesis of these 2 cultures is the only reason that Europe was ever able to exist and thrive. And it's not a coincidence to me that the first large civilizations of Europe were created by people who were effectively EEF, with an indo european warrior culture. What made Europe successful is that it was a combination of Mesopotamian civilization building and steppe ethos and religious beliefs. And the western hunter gatherers uhhh... they definitely existed. Wouldn't have blue eyes without them so props to the ooga booga people.
