Yes, let's not mistake understanding for sympathy. How to stop the problem? This is such a deeply ingrained problem in human society. There is not the space here to address an in depth analysis of what constitutes child abuse. We must all learn to be observant of the children around us -- listen to them; care about what their lives are like. Do what you can to help a child that you suspect is being abused. There are blatant forms of child abuse that must be reported to authorities. Less noticed forms of abuse, such as a parent constantly yelling at a child or belittling a child (there are many more such manners of abuse that escape me at the moment) must somehow also be dealt with. Wars teach children that solving problems by killing the enemy is okay. It also teaches them that its normal to have enemies which need killing.
We could peel back layer after layer regarding what societies teach children that constitutes child abuse, what parents teach their children, what schools teach their children.

In my heart I long for a Utopian world where children are not abused, but are each raised to reach their greatest potentials. I wonder if the human species will last long enough for that to happen. Grown human beings, who were most likely abused in some fashion, are responsible for raising their young. Abuse seems to be passed down from generation to generation. There are those who realize that they were abused and try to the best of their ability not to pass on the abuse. This, at least, brings about some change.
This post makes me think of a documentary I saw that was titled something like "The Dancing Boys of Afghanistan." I cried for those young boys who were being taught by adults in their society that this practice of pedophilia was normal and acceptable. Imagine the confusion of those young boys -- being made to participate in something that didn't feel right to them.
Sorry for my disjointed thoughts here. I've had to stop myself from saying more. I was unable to listen to the music via the link that was provided, as when I was redirected to the site there was a message saying the site was private. I've possibly missed the point of the forum due to not hearing the song others spoke of in their replies. I only know that child abuse is deeply rooted in human culture at many levels. Education must be the answer. Along with locking up the worst offenders, even though we understand why they have offended.
