Arguments against existence of God.

[Bucky Ball]

No sorry, cherry picking definitions doesn't work on me.  Try again.

You have religious claims, organization, protections, collect offerings that are tax exempt, and make claims beyond the scope of how said agency is defined.  I live in the United States of America.  Here you are both legally and empirically a "religion" with said protections.  To discount the Chinese is also irrelevant because their definition differs from your said definition and their primary religion is atheism.  Your opinion doesn't dictate anything beyond the scope of who you are.  If you say you are an atheist, that's your opinion.

I have no religious claims ... you have demonstrated NONE, I belong to no organizations, (by that idiotic definition, golfing would be a religion, as well as ANY organization where its members have anything in common), protections apply to many groups, not just religious, so fail again, I collect nothing. 

If a religionist says they are a person of faith, it's nothing but their opinion.

Here's the definition of religion. Atheism meets none of the standards of these definitions.
Do try harder again, next time.

If you're trying to make a case that no one actually knows what they think, and YOU know better, .... good luck with that one.
