Apog - Ethics are not a matter of popular opinion.
Here is the response to your point from the summary...
This answer requires that we unhitch the word "love" from any meaningful definition. We may think we know what love means but god demonstrates that we have not the slightest idea. Love could just as easily mean the capricious annihilation of a quarter of a million innocent people. It destroys our ability to make moral judgements. "Good" is whatever pleases god from moment to moment. Mass destruction is just as morally good as altruism and self-sacrifice.
If god is love, everything he does must be motivated by love, even when he judges. Love is not a hat he can take off for a while and replace with one labelled "vengeance".
Ethics become a matter of divine fiat and the value of human life is trivialised. This defence reduces god to a celestial Pol Pot who may choose on a whim to eradicate our lives in the manner of the killing fields of Cambodia.
If you are suggesting that we need to justify the statement that drowning a quarter of a million people is not loving then theism has given up the fight.
So far nobody has suggested how we hold on to the power of god to avoid the devastation of tsunamis and the love of god with the fact of natural evil.
