Question for Atheists

[Mister Agenda]

*I feared that this would happen

I'm afraid I can't agree. Both have very specific meanings, and they aren't the same.

Anti-theism has 4 meanings:

1. Belief in the non-existence of god(s)
2. Belief that religion/religious organisation should be opposed
3. Belief that god(s), if it (they) were proven to exist, should be opposed
4. Opposing belief in god

1. is the same as 'gnostic atheist'. Further, I contend that it's a more accurate usage due to the etymology.

What is your source for these definitions? None come up on the first page of GOOGLE where 1. is listed, let alone listed first. Dictionary definitions are listed in order of most common usage.
