People that are abusers (emotionally or otherwise) are people that have been abused, or are somehow damaged. Based on the prevailing thoughts on psychology and development, anyway.
This does not excuse the abuse, it's simply a dynamic of the equation that needs to be solved. People that hold no value, respect, or love of themselves will hold no value, respect, or love of others. This is what a sociopath is, and according to developmental theory it is determined before the age of 5 to 7.
My solution is to round up abusers and ship them all to a secure island where they can abuse each other to their heart's content. However, that's a rather abusive solution; and since I'd rather not be sent there I can't really advocate it.
Which illustrates another dynamic to the problem: how do you find a solution that simply isn't hiding the problem and creating more abusers that will eventually abuse someone.
An interesting dynamic is that many abusers find solice in religion. Which can be great from a social and cultural perspective to help prevent abusers from abusing. However, it doesn't seem so straight forward. Simply consider the article and the number of people that abuse in the name of religion.
And now we're back to complete the circle.
Just like the screw'd up Israelis and Palistinians. There is no solution until one, or both, of them exist no longer.
