Ok, let’s assume it’s wrong.
What about the Ten Commandments, and all the cultural conditionning against murdering then?
Grossman’s point would still stand: FPS deactivate the resistance to killings one human that has been informed since the Ten Commandments (at the very least) and in other codes as well (such as hummurabi’s).
FPS can't de-activate something that was never activated.
Communists have pushed to keep the Ten Commandments away from people that turn into mass murderers. They reap what they sow.
If they aren't being taught the 10 commandments, there's nothing there to de-activate.
Very bad logic and form. You lose face.
