are you freakin kidding me?!!! This thread is spanked children having lower IQs. About how some parents assault their toddlers and older children and choose to call it 'spanking' or 'swatting'. AGGRESSIVE IMPULSES should have no place in child rearing.
So, in your vocabulary spanking equals with assault? By your way of seeing things that means every slap, every rougher physical contact with kids equals with assault. Where is your proof that those parents aren't just spanking, or swatting them?
If that were made into law, then this would mean that the prisons and courts would be overrun with such causalities even more than usually.
Where do you draw the line? What's next? Nudging someone will equal with attempted murder, yes?
