The most disgusting christian content you will ever see.

My point is, the atheist church is a religious organization:

http://en.wikipedia.org/wiki/Religion

A religion is an organized collection of beliefs, cultural systems, and world views that relate humanity to an order of existence.[note 1] Many religions have narratives, symbols, and sacred histories that are intended to explain the meaning of life and/or to explain the origin of life or the Universe. From their beliefs about the cosmos and human nature, people derive morality, ethics, religious laws or a preferred lifestyle. According to some estimates, there are roughly 4,200 religions in the world.

And doctrines don't have to include God in order to be a doctrine.

doc·trine
/ˈdäktrin/
noun
noun: doctrine; plural noun: doctrines

a belief or set of beliefs held and taught by a church, political party, or other group.
"the doctrine of predestination"
synonyms: creed, credo, dogma, belief, teaching, ideology;

What "organized collection of beliefs" would you be referring too? Atheists have one thing in common: we don't have a belief in god. How humans relate to the cosmos isn't part of that definition nor is where morals come from. There's no atheist ideology, dogma, world view, etc.
