Fact: No child, anywhere in the world, will ever be abused or not abused based on whether your Facebook picture is or is not a cartoon. Changing your Facebook picture isn't going to prevent child abuse. and It's not going to cause it either. If you don't believe me, ask Snopes.
I'm all for ending child abuse. But this campaign is going to do about as much to help that goal as Kim Kardashian not tweeting for a day is going to end AIDS.
