It’s true that social norms change over time, and we often reassess past practices with new knowledge. However, just because something was widely accepted in the 80s doesn’t mean it wasn’t harmful. Many things that were once considered "normal" like leaded petrol, smoking in restaurants, or children not wearing seatbelts are now recognized as dangerous, not because society is "soft," but because we have a better understanding of their effects.
The idea that judging past actions by today's standards is "moral anachronism" only applies if there was no awareness of harm at the time. But even in the 80s, people debated whether smacking children was necessary or beneficial. Psychological research has since shown that physical punishment increases the risk of anxiety, aggression, and strained parent-child relationships. It’s not just a moral shift. It’s an evidence based understanding that smacking doesn’t achieve what people once believed it did.
The comparisons to child marriage or Roman era slavery are misplaced. Those were acts that some people at the time did condemn, just as there were always people against hitting children. More importantly, just because something was accepted in the past doesn’t mean we shouldn’t re-evaluate it. Society progresses by learning from mistakes, not by defending them just because they were once common.
Hitting children is, has always been, and will always be abuse whether you want to accept it or not.
Imagine being a 3-4 year old who had eloped, because that's what she did, she eloped for whatever reason, into the road, getting yanked back, car whooshing past, scared out of your wits and then to top it off your mam cracks you because she is not in control of her emotions. How terrifying for her.
Also I'm no stranger to children running off. I have an autistic child who is significantly speech delayed who has eloped. He is a young child, yes, he has limited understanding for logical and rational communication, but I'd never hit him because he has a limited capacity for understanding words, or because of my own emotional upset.
Everybody else with young children manages to understand their children's developmental capacity for understanding danger at the roadside without resorting to assault.
Stop using false equivalence to continue to justify hitting your child.
