Sara2001 I haven't talked about spanking kids but spankings in a relationship.
Did your spanking started when you was 18 years old?
Did spanking started when generation before was 18 years old?
You talked in a general way and not specific about spanking an adult agreed to it. You referred at the common way which was happen at home, school, apprenticeship and sometimes at work. It has a long-term effect and you find sufficient literature and scientific work about the topic.
Sara2001 Where is all the irreparable damage in almost any family for the last 50.000 years?

Now show me a reliable source which proofs it has no a long-term effect. You state only phrases without any scientific proof which we can find at typical forums and blocks where everyone quotes the other without being able to name a reliable source.
The argumentation that if something was practised for a long time, it' well know, is not proof. I can give you enough examples.
Sara2001 I haven't done a research, but I think it was kind of the norm or at least much, much more common.
Here you say it yourself that you have not checked it but claim it with a certainty that lacks any basis. You have no idea how it was for them at that time.
