Long ago, I used to be on board with the "hit them until they correct course" method, perhaps due to my own upbringing. (Please don't misread, I don't mean like brutal, damage causing engagements, just spankings and the like)

What changed my mind was having a child. The first time I went to spank him, I felt so damn bad. Looking into his eyes and seeing the fear and hurt from what he could only perceive as betrayal. It was too much.

The other thing I have been considering lately is, when you spank or harm a child because they don't obey, you instill in their minds that "authorities" have the power or even the "right" to inflict harm, you lock them into a mentality that says it's ok for the "powerful" to harm those weaker. That it's ok for men and women in government costumes to inflict violence upon you or anyone else because of "non-compliance".

I don't believe any of those things. I believe the opposite in fact.
Thanks for the book suggestions! Now I need to find out how to trade my Crypto for books.
