After our recent major loss of life and property, thousands of people and many organizations stepped up to help. The list included churches, benevolent groups with religious ties, and even local casinos. What you did not see on the list were groups who have been critical of religion and are unbelievers in God.
The Freedom From Religion group got the 10 commandments removed from an Oklahoma school, but they could not be bothered with helping the victims of the storms. Neither could you find the ACLU, any agnostic or atheistic organization, nor anyone or anything associated with the Humanist Movement on the list of those who were helping the hurting. People who are members of these organizations are conspicuously absent whenever people need comforting, whether it is from natural or manmade tragedies.
Like I said, you have to try really hard to avoid finding evidence of atheists helping out tornado victims.
