S.E.
I was spanked. Neither me nor any of my sibling are violent. My husband was spanked, neither he nor any of his siblings are violent. Most of my friends were spanked. NONE OF US are violent, into drugs or alcohol, or have had legal, emotional, or mental problems. In fact, we are all healthy, college educated, well adjusted adults.
But here's the difference, spanking was not the go to punishment. Nor did it follow us beyond elementary school. It was used where other punishments would not be effective and there was always a warning involved. It was not used to inflict pain (although it was uncomfortable) and no 'weapons' were used. It was to meant to make us aware that we had crossed a line that should not be crossed again. The few times it was used it was effective. but had it been used more, it would not have continued to be so.
