My mum's Asian, born in Africa and married to my white, English dad.
My mum would beat the living daylights out of me when I got into my teens, shoes in hand and everything. It didn't hurt too much as I got older and older, but when I was younger (5-10), she would still smack me if I really wound her up. Enough to leave a red mark if on bare skin, little else.
My dad would just scream at me, much more scary imo.
It's entirely ridiculous to think that this has negatively impacted me. They're supportive parents who've provided me with everything they could work for and I live a decent life because of that. Teaching discipline, courtesy and manners to a child is literally the most important thing a parent can do. If you do these three things, you end up with a kid who's gonna be confident and well-rounded because to do those three things, you need to nurture them quite a bit.
If you smack kids so hard that you're cutting them or bruising them, you're not teaching discipline and it shouldn't be called 'discipline'. That's pure violence and it's unacceptable, clearly. People really need to learn how to differentiate.
