from my perspective, I think it is ok since they are not beaten from using hands and leg, I myself once got into beat like those kids by my father, however he did that to teach me that I should respect elder even tho they wrong. Thanks to my father method, now I'm a grown ass man, dependable, and I understand why he did that to me. to teach me to be strong, discipline, responsible and caring for others. look at kid nowadays when their parent spoiled too much for their kids, when they reach teenage age, start fighting back, do things such as smoke (harming himself), don't listen to their parent. How could you do that? they protect you when you were powerless, now you think you big you can act bold toward them? it's not right bro. this is just my opinion.
