This chain of training from human to human, from generation to generation, is perfectly normal in human society. You don’t need to blame your parents for teaching you to be like them. What else could they teach you but what they know? They did the best they could, and if they abused you, it was due to their own domestication, their own fears, their own beliefs. They had no control over the programming they received, so they couldn’t have behaved any differently.
