I already agreed that 1 death from a natural disaster is just as much a fatal blow to christian theism as 250 000 deaths.
Flamegrilled is asserting that there is evidence of a loving god and therefore the fact that he invented tsunamis and allowed one to drown a quarter of a million people is not a problem.
Imagine you thought you knew a friend really well. You knew he was capable of being kind and generous as he had demonstrated many times. Then to your horror you discovered he regularly beat his wife and children. You had proof to this effect.
It would be foolish of you to overlook his violence as if his moments of kindness made it of no consequence. You would need to put your emotions aside in order to form a more honest appraisal of your friend.
Similarly you need to face up honestly to god's abuse of the human family he claims to love.
You are like a character witness in the dock complaining that the prosecution keeps going on and on about your friend's violent crimes and forgetting how much he gives to charity.
