Religion
1 the belief in a superhuman controlling power, esp, in a personal god or gods entitled to obedience and worship.
2 The expression of this worship
3 a particular system of faith and worship

Atheists are all different so there is no system, don't worship science coz that changes, whereas you have to worship the static.

Theists are always referred to as sheep or as the flock coz they are easy to control and will go wherever you lead them. Atheists are cats, ever tried to herd cats?

Sorry, not in your club, not a religion.

I don't go to mythical places with strange men.
