I want to try to explore the obvious gulf between the two sides of this discussion.
To us atheists a quarter of a million deaths is a tragedy beyond description or comprehension.
Every one of those individuals really perished. They were not fallen sinners, they were not "dead in their sins" or "children of wrath" as the bible claims. They were people just like us. People who loved their families and who had dreams and ambitions for themsleves and their children.
There is no superstitious platitudes that can be mumbled to make it all better. All of that human potential is lost, gone for good.
Life, this human physical life really matters to rational people. When tragedy strikes we can't take refuge in comforting stories about spirits and eternity.
To theists, regardless of claims to the contrary, this life is relatively unimportant - when they are talking about the lives of others at least.
To them this world is broken and temporary. Humans are sinful enemies of a perfect god. Death is a temporary inconvenience - apart from their own death of course. Tragedies on the scale of the Asian tsunami are something to be wrestled with intellectually. The existence of a loving god is a given that is not open to debate.
This is why we hear theists repeatedly complain that atheists appeal to emotion. Yes we do. We rely on evidence and reason but we also deal with the reality of suffering and eschew ivory tower theories.
I have been on both sides of the divide, but when I was on the theist's side I was incapable of approaching human suffering like it was a theological sudoku puzzle.
