@FriendlyReminder I am very sensitive to it. I can remember being smacked by my father. I can't remember any of the things I supposedly did wrong, but I can remember the terror, and I can remember begging him not to and being ignored. I never smacked my own children. I was definite that it wasn't happening. I came to the conclusion that even if every parenting expert on the planet said it was the right thing to do, I still wasn't doing it. If it's assault to wallop an adult, then it's assault to wallop a child. AFAIK, my sibling, who is a lot younger than me, wasn't smacked. I never threatened to drive them to the other side of town and leave them there, to knock their block off, to knock them into the middle of next week, or any other variations on that theme. I have a very low opinion of adults who do it. I also can't cope with swearing or aggressive behaviour. I just have an almost uncontrollable urge to hide, even if it's not directed at me.
I think there are two things going on: I think some people did have those experiences and are able, because of temperament, the wider family etc, to be minimally affected by them. However I also think that a lot of people can't really face the truth about their parents. I don't judge them for it. Facing the truth about having been badly parented is very, very hard, not just because it means accepting painful things about your parents, but because it also means accepting painful things about yourself, that there is damage, that sometimes because of the damage you behave in ways that aren't good, that your responses aren't always healthy. This can be a really scary rock to look under.
We know how common child abuse is because we lived it. It's not some rare thing that happened to other people far away. It happened to us, in our homes. We are the walking wounded. It makes the world really difficult to navigate. Are we over sensitive, or are other people just really effing naive? Both things are probably true. All I know is that there's no abuse in my house now, where I live, where my children live. That's the best I can do. FWIW we got new neighbours about 18 months ago and she screams at their kids. I have to hide in the garden when she starts. Literal flight.
