Grimjim, I certainly don't think that this has just started happening as your post seemed to imply. This has being going on forever. The hatred for others not like themselves started long, long ago and the only thing that has changed is their ability to do harm to others. The hate has been passed from generation to generation for so long that no one knows when it started.
As I said, I think anyone who does great harm to a child, mentally, physically, or in any combination like these people do deserves a special place in Hell and shoud be helped to start their journey to that place as quickly as possible.
