I don't want to see those things either. I don't go on Facebook for some historical reality check, or to be reminded of the horrors that are happening around the world. Every news media organization sensors itself and doesn't show the full extent of the horrors it reports on b/c it counterproductive. It's upsetting and it ultimately just desensitizes you. I think that this photo has already been overused and turns into something like an art piece. If you had a similar new photo of a traumatized naked girl after, for instance, a recent school shooting in the US people could feel a lot more shocked than when they see this photo for the Nth time - and people wouldn't object to it being removed.

You have to draw a line somewhere. No naked children or gore seems reasonable.
