Two thoughts on the subject.
1) Wow, what a way to show your kids you love them. Look at me, I set myself on fire for you. Screw the fact that I just scarred you for life by doing so.
2) The punishment was excessive based on the facts presented in the article. It seems there is probably more to the story than told, but if not, the legal system was out of bounds IMO. I don't condone smacking your child, but certainly parents have done far worse to their children and retained custodial rights. IF the story is true as presented, then it does serve as an example of how the govt is slowly taking away parental rights. I believe a parent has the right to spank their child(though I'm sure some will disagree) as long as it is not excessive. My father tanned my hide when I did wrong and I learned my lessons. In today's world, that runs the risk of being called a child abuser. I never thought of it as child abuse. I knew my dad loved me and I knew he did what he felt he had to do to teach me a lesson. And I learned my lesson 95% of the time.
When you take away a parent's right to discipline his/her child, you remove their authority. Any child not happy with a parent's decision can willfully ignore it and know that their parents have no recourse and that should a parent take action they can call and report abuse. I'm not advocating child abuse, but I am advocating parental authority. People can argue using time-outs or grounding your child, but what do you do if the child refuses to obey? Children need to respect their parents, but quite honestly, they need to have a little fear of their parents as well. Not a terror, just a fear of being punished.
The children of today are far more pampered than the children of the past. Gone are the days where children had to help in the fields. Instead they play video games and go to the mall. I see kids disrespect their parents in public all the time now with no consequence. You can tell the parents are afraid to take action. The one time I disrespected my dad in public, he whooped me on the spot and I never did it again. While I believe in protecting our children, I think we as a society have stepped over boundaries we should not have stepped over. I think we have thrown out reason in our efforts to appear "civilized".
