In my homeland many things have changed within last decades... My parents are from the generation which was often physically punished and even my older sister got beaten few times at school with a ruler. I have never got hit but as I was from a small village, some of my schoolmates still got beaten by parents, so I think that many adults in my homeland have been beaten during their childhood but not all of them need a therapy because of that... I would never hit my children but I guess that it was so normal then that children took it as all other punishments (like now no using a computer for some days). Of course only if parents weren't sadistic anyhow... I don't know, I don't know how someone could hit a child but I also do not understand how difficult life was then...
With respect to therapy, in my homeland it is still something really weird and no one would never admit that she/he goes... Probably it will change within next 20 years...
Here, it might be a bit more okay to be in therapy but for sure the level of acceptance is still not the same as in US...
