I agree that the media tends to concentrate on certain things, and I think the defining line here is that it is about where it happened, not to whom it happened to. It's a cultural thing.
As to the forum, well look at the threads - the ones that go on and on and get everyone fired up are about the differences between one another, or what bible do you read, or the end times differences of opinions- different things rile people up. Good distraction tactic on the part of the enemy don't you think !?
I do see what you are saying, and I put my hands up and say that sometimes things from outside my own culture do not hit the same depth, but, as you say, these things are happening to brothers and sister in Christ - and they should matter. I think God needs to do some work within me on that one -
I equally think that sometimes we are pulled to have compassion on different things, just as we are led to pray for different people.
