Identity cleansing has been practiced by many in many countries. We have done this against the native Indian people without any regrets. Israel has been doing it on Palestinians for ages. Now Milosevic is doing this to Kosovars. Family cleansing has been with us for hundreds of years and the media have intentionally failed to bring it to light.
Reasons are many.
Some are minor and many of them are of criminal nature. Yet they have not been charged or sent to prison for participating in crimes against humanity. The systematic destruction of the families is predominantly visible in our societies these days. Media are well aware of this for a very long time. The failed justice system and criminal conduct of the judges, lawyers, and police are few of the reasons for family cleansing.
