This should really help the situation.

Gotta love when people hit you with this one, after a natural disaster. God is the one who wanted this to happen to them...haha.
He causes the disaster you idiots. 
There is a saying and it is
very true - Christians will
pray for you and muslims will
prey on you.
I tend not to belittle those that have a real faith in Jesus, even though I myself am an atheist. What constitutes a real, genuine faith in Christ? They live it not just speak it. I know a few that do just that. So then, either join those with a genuine faith in God in hoping the best for the Japanese people either through prayer or in just well wishes that mean nothing more than you truly do wish them no harm but instead all the best because while not everyone can or will give money, food, etc. (and that is just the way it is) just about anyone can give more than a flying fuck about the loss of life and property. Or you can...
Continue to make yourself out to be childish, heartless bastard, which I don't for a minute believe you to be.

Don't get me wrong, I don't believe any more in prayer than you do, I'm just a touch more polite about it. Except in the case of islam, fuck that noise.
