The question isn't, "is spanking violence?"
It's "are norms changing around whether spanking is socially acceptable?"
And now, for a lot of people, no, it isn't. Hitting a child to punish them is no longer "the basics" for a lot of people, even if it's how a lot of the older generation grew up and took for granted.
I have no kids, but most of my peers do now, and spanking is sooooo much off the table, it's on par with overt racism (saying the n-word, saying discrimination is okay, etc). Absolute social taboo, and absolutely no question that it's "physical violence".
What definition of violence are you using which doesn't include hitting children?
But let's go with your incorrect assertion that it doesn't cause harm. Try slapping one of your co-workers, and then in court saying "but it was a completely non-injurious form of discipline" and see how far you get.
All that said, yes there is a difference between parenting and abuse. However, children are not tiny adults. They are tiny humans. You can often tell how they are feeling or why they are feeling that way, but it isn't by thinking the way a well-adjusted adult would. The whole point of parenting is to help them get to that point eventually.
If someone acts the same way at 25 that he acts at 13, that person would be a sociopath. But 13-year-olds are rarely sociopaths (i.e., they are only when truly mentally ill).
Children can't function the same way adults do, and we can't treat them the same way, full stop.
This is the kind of willful obtuseness the poster upthread is talking about.
I'm just saying that hitting a child is always as abusive as hitting an adult, and often more so because the child has no chance of escape.
There are many ways of parenting, and msot of them do not include violence against the child.
This is why hitting children is illegal in many countries.
Never mind treating children as adults: how about we treat them as humans, with rights that need to be protected?
And that's pretty much the key point. You cannot pretend children are adults.
Also, this is why you should be a patriot and subscribe to Science rather than Nature.
It's always been physical violence, it just used to be universally accepted physical violence, just like beating (and raping) your wife was. Now it's become less accepted, just as the other two have.
Children are not rational creatures, or at least not always, once you get to a certain age. There are only so many ways to deal with them, and in my opinion, as the father of 4 adult children, spanking or similar correction may be called for in a situation where the child has put himself or someone else into danger.
Because there's one thing people who aren't around children don't understand and that's how many times the average child escapes serious injury or even death. I've seen many situations where no one is being negligent, but which serious, even fatal injuries could easily have happened. You might have the most "enlightened" attitude towards discipline in the world, but that can all change when your child rushes out into traffic or does something else equally dangerous.
Of course, in response to the inescapable dangers of life, we are more and more seeing parents who simply don't allow their kids to be exposed to any source of potential danger, and they grow up to be completely helpless and start voting socialist.
