...uhm, what?
It's humans killing humans no matter what ****ing color they are. It's just as horrible for a black person to kill a black person as for a white person to kill a black person or a black person to kill a white person.
Because the people being massacred by the LRA are the same color as their murderers, it's okay to not care? What the **** is wrong with you?
Believe it or not western countries largely used to be just like that, endless wars, both civil and foreign, looting armies ransacking helpless villagers, yes we've seen it all before. But now, mostly, those days are gone. France, Germany and Britain aren't having they hundred years wars anymore. Western europe evolved out of it, but the africans didn't. Eventually they probably will, but not for a long time.
Take a good look at our history, and you'll find many parrelels with what is happening today in many parts of the third world.
