It’s not very “alpha” to line up naked women and shoot them in the back.
First of all, I'm not sure about that at all. Warlike cultures do engage in atrocities all the time, along with doing things that involve more bravery.
Second, I don't understand who that is in reference to: the Germans or the Russians. Neither of them gets off the hook for atrocities.
I'm saying that this whole idea that Germans changed because of a change in the gene pool rather than because of culture and their experience of history is bunk.
The phrase "alpha male" came from somebody who has that theory, and doesn't reflect my own view.
