Can't remember the last atheist group feeding the poor and hungry, but seem to recall many groups or various religions helping the multitude.
I don't recall any non-stampcollector groups feeding the poor and hungry either, but I bet a lot of non-stampcollectors do. Atheists don't generally come together as a group, neither do non-stampcollectors. And atheists don't force their views on hungry and poor people when feeding them, they just feed them, which makes them better in my view.
