You ever wonder how trauma is passed through generations? Because of the premise you are saying: people in denial about a trauma they experienced. They assume the shitty experiences they had are normal and then repeat the same acts that were visited upon them.
In my reading about cptsd during my counseling (uh oh, am I playing a victim?) one of the most common thoughts identified in childhood trauma is downplaying the severity and assuming it is common. That leads to people not seeking treatment.
Try showing some compassion and assume good faith.
