D12, there were several organised atheist groups that helped mentioned in the article.
Unlike the christian groups though, they obeyed christ and didn't trumpet their good deeds from the roof tops.
"Let’s make this very clear: Atheists were in Oklahoma doing everything Christian groups were doing — including handing out hot meals. To suggest that we were not there and not doing anything useful for the victims isn’t just factually wrong — it’s slander against all of us who don’t believe in a God.
If Klein had mentioned any other group of people — “funny how you don’t see organized groups of Jews giving out hot meals” — you know there would be hell to pay."
