I disagree with the definitions in the sticky so this is a thread where everyone can discuss them.
If you disagree with religion then you are non-religious. Meaning religiosity isn’t something you take part in.
Right. I think that it's important to note that 'theism' isn't synonymous with 'religion'. It's entirely possible to be be a religious non-theist. Millions of Buddhists, Jains and Confucians would fit that category. It's also possible to be a non-religious theist, I guess. Maybe some of the 18'th century deists would belong in that one.
It might also be helpful to make a distinction between 'non-religious' and 'anti-religious'.
Atheism isn’t a worldview, yet it is the denial, doubt or rejection of any belief in god or the possibility that any god (could) exist.
I don't think that all atheists would deny any possibility that god(s) could exist. They just don't believe that any do.
If someone doesn’t believe (whether it be in rose petals, goblins, their spouse or god) then they are an atheist.
The 'theist' in 'atheist' seems to suggest that atheism is specifically concerned with non-belief in the existence of god(s).
There is no room for skepticism other than some quack ideas about something they know little to nothing about, that nothing being god – if god exists, because atheist don’t know and don’t care to know and tend to follow the same old false dichotomy like many theist. This is a black and white way of thinking (example): “It’s either my way or the highway!”
If you're suggesting that some atheists seem dogmatic in their beliefs in the non-existence of god(s), in much the same manner that some theists are very dogmatic about their belief in the existence of the same things, I'll agree with you. I think that there's a certain kind of atheist who really does resemble a religious fanatic. Except that in the atheist's case, it's anti-religious fanaticism. The style (and abrasiveness) can be very similar though.
Agnosticism is like a wacky conundrum that people sometimes mistake for atheism, which it is not. It is a position of neutrality between atheism and theism.
Agnosticism is the belief that knowledge about transcendent things (like gods) is lacking. It's entirely possible to simultaneously be an atheist and an agnostic.
I personally consider myself an agnostic. I don't know of any way that human beings like myself can obtain objective knowledge of transcendent things, should they exist.
Beyond that, a lot depends on how we choose to define the word '"God". If the word is being used to refer to philosophical functions such as the universe's first-cause or ground-of-being, my attitude is basically non-committal. I don't have a clue why reality exists instead of nothing at all.
But when we are using the word "God" to refer to the specific deities of religious tradition such as Yahweh, Allah and Vishnu, then I would qualify as an atheist as well as an agnostic. That's because I'm confident that whatever the unknown first-cause and ground-of-being of the entire universe might be, the chances of them turning out to be one of the cosmic "persons" described in the earth's religious mythologies seems so vanishingly small that I feel quite comfortable thinking and behaving as if those religions' theistic claims aren't true.
I don't believe that Yahweh, Allah or Vishnu literally exist (outside our mythologies at least) and I'm reasonably certain that none of our religious traditions is in any better position to answer the ultimate questions than I am.
