It is what the BBC is reporting. It offers proof here.
I find the whole thing is based on confirmation bias: Come up with an hypthesis and then look for proof to back it up.
As an Atheist I do not believe in a God, nor do I see a need for a God, but that does not mean I am devoid of morals. I would argue that in many ways my morals are superior to those whose morals are based on a religion and their belief in a God. Theirs are based upon an ideology and a God, of whom they have no proof, and what that ideology tells them is right.
Mine are based on what I observe in my daily life and how I would wish others to treat me as I do them. They are in no way inferior to anyone else's.
Morally depraved I certainly am not.
