Well it's kind of right, given that atheists used to get out to death by the religious types back in the middle ages.
That is also utter nonsense.
Religion empowers and makes individuals stronger. Look at history and you will find those persecuted became stronger as they clung to their religious beliefs. History is littered with survivors born out of religion.
Even now, when people face adversity, they turn to religion.
I don't know of any atheists who are survivors. Atheism by it's very nature is about giving up in difficult times. It offers no hope or redemption.
Survivors are not born out of Atheism.
