The thing is it’s embedded on us Asians that we must respect our elders, and that getting hit is something that would result if we did something wrong or didn’t meet the standards of our elders.
Even if those elders are at wrong most of the time you just gotta hold it in to not be told ungrateful or disrespectful
You know deep down we just can’t… we are always taught that you are what you are today because of your parents… they are your gods… so we are so thoroughly brainwashed with that idea that no matter what they will do even talking back would put us in so much guilt that we would regret it afterwards even if we were right…
And also we would be considered toxic selfish bish if we hit the hands that raised us and feed us and did sacrifices for us…
Corporal punishment is very much the norm here, as well at its been deeply ingrained in us how we must respect elders and be thankful to the life they gave us, that combination creates a cycle where hitting children is normalized and justified as "I got hit and I turned out fine" type of people. It has also been scientifically proven that corporal punishment does not work at all.
So talk to your kids when your giving them punishment people, so they understand what they did wrong and what the punishment is about so they truly understand why the punishment is happening.
I seriously hate the notion that you must ALWAYS respect your elders even when they are blatantly disrespectful or even abusive toward you. I also hate that physical discipline is so normalized in Asian countries. You are so right about respecting someone who does not respect you. Ofc respect is expected, but the moment they give you a reason to not respect them anymore that’s that.

Genuinely asking: I'm not very familiar with Korean customs. Is it common that parents hit their adult children?
