But atheism isn't a religion, and doesn't need converts. There's nothing to follow...
If they don't need converts, why do they need advertising? If there is nothing to follow, why are they having a convention?
Atheists teach atheism.
Atheists pay to advertise atheism.
Atheists have conventions to discuss the merits of atheism, and how to spread the atheist view.
I'd be willing to bet that there is a non profit atheist group that doesn't pay taxes.
This all sounds very familiar to me.
