LPH... I'm one of those who's just sane enough to know that I would have been (hopefully almost, but quite possibly entirely) as damaging to a child as my parents were to me, so I refrained.
I have no doubt that having a child changes one's perspective - I have no doubt that that's a lot of where those looks of pity come from (Oh, man, those looks of pity, and IMO there's a good bit of judgment and accusation mixed in with the pity, too.)
But. My adult life and my healing has largely been about getting past the excuses, rationalizations and justifications that my parents always had. They were under stress, they were abused children themselves, yada, yada, yada. Understanding what happened to them in no way diminishes or invalidates my pain or my sisters'. They're different events that happened in different peoples' hearts. There's a causal relationship, sure, but the fact that my parents were abused as children doesn't mean that I wasn't.
