Atheist is irreligion.

Irreligion is non-religion.

If you think atheism is a religion, what are their core tenets?

What are their holy books?

Horseshit. The old atheist saying is "Not bowling is not a sport" Well if you have not-bowler clubs that get together and talk about how great it is to not bowl you are a sport of sorts,

Nope. Not bowling is still not a sport.

IF a system of ideas not containing a deity is not a religion then Buddhism is not a religion and Scientology is not a religion.

System of ideas? Atheists don't have one.

For example those who follow material nihilism are distinct from Buddhists (most of who are still technically atheists, along with Satanists and some of the occultists).

Which warrants a correction to my previous statement: "Atheist is irreligion" because Buddhism can be called a religion... or a philosophy. Depends on the definition of "religion".

Well scientology has no gods either just aliens.....

They'd be about as religion as Buddhism, then.

Kind of doesn't matter, the IRS has classified some secular organizations as churches and granted them exemptions

But where as Buddhism can be a religion, atheism as whole is not.

And neither is "theism".

"Theism" is not one, singular religion. It's a category that contains all religions that believe in a god or gods.

>System of ideas? Atheists don't have one.
Not true at all

"Atheism" is not religion. It's a category that contains religions that don't include god or gods, as well as irreligiousness.

@ETBrooD What is the system of belief that **ALL** atheists hold true?

That wasn't your claim

You said atheists don't have *a* system of ideas, which I read as they don't have any system of ideas

Well, if all atheists don't have **one** system of belief, then atheist don't have **one**, by definition.

You mean atheists don't have a monolithic idea?

I said atheists don't have one.

Atheism is a collection of many beliefs, so there's more than one.

@ETBrooD **DUH!!**

Atheism includes materialism and Buddhism.

Are they the fucking same thing?

But not a single religion has a monolithic system of ideas either

Fucking retard.

What is the system of belief that all Christians hold true? Spoiler; there isn't one. People hold belief systems. At the time of the Founding those were all religions so they wrote it in those terms.

@Jym Jesus?

Christianity has a variety of systems of ideas

Same for Islam and Hinduism

@whiic

Which Jesus? Which version of his teachings? As varied as the atheistic religions when you examine it.

All Christians believe in Christ. The Bible. What other Jesus?

That's not a system of ideas

That's just the basis from which they derive, or attach to, a variety of other ideas

Is agnosticism a religion too?

Non-religions are by definition not religions

But atheism is a religion?
