"Well the data on the divorce rates is pretty clear."
I am aware of no data that links spanking to divorce rates, positively or negatively. You are comparing apples to oranges here.
And I guess you see nothing wrong in bullies, in adults hitting children. Because no matter the euphemisms you use, spanking is an adult hitting a child. Using hitting or the threat of hitting to force a weaker person into compliance is bullying.
No, I don't see a problem with a parent hitting their child with the caveat that it shouldn't be done excessively (as defined by law). Your comparison of parents to bullies is unfair and inaccurate. I don't recall ever seeing a bully in school hit someone because the bully wanted to ensure the safety and social adjustment of the person he or she hit.
" And as your lack of willingness to own your behaviour indicates - it clearly did NOT work for you."
Let's see, no criminal record, good job, happy marriage, active in my community. Yeah, I'm a complete failure. Those horrible spankings I got made me a monster. More seriously, one could argue that since my example is only anecdotal, it isn't representative, yet the amount of anecdotal evidence arguing that spanking is not harmful is truely huge.
" they also believed that if you sailed too farr from shore, you fell off the earth. You want to joint that level of rationality? Well no one can stop ignorance.
The "falling off the edge of the earth" belief is mainly a myth. The greeks believed the Earth was a sphere, as did many other ancient cultures. Besides, you are commiting another fallacy in assuming that one inccorrect belief means that another completely unrelated belief is wrong. "
My point about the billions before us is merely that if spanking were in fact as harmful as you imply, then it seems strange that western civilization would have reached the level it has. Even if you were to convince me that spanking was harmful in any context, you still would need to convince me that its harm outweighs the harm of millions of people not using corrective techniques (or more accurately, misusing them) on their children.
Finally, what many anti spanking zealots refuse to see is that every kid is different. My wife was spanked maybe once in her entire life, she was just a good kid. You give my toddler to my goodmother and she can't figure out what to do. Time outs and such just don't work. And just spounting off about "the cycle of violence" does not make a very convincing argument.
