''Atheism isn't a belief. It is an attempted belief. It is a self-delusion of the atheist. Atheism isn't a belief because all - 100% of - so-called atheists know that God might exist somewhere that they haven't discovered, yet.'' Well yeah, thats why it's a non belief. Atheism is usually not saying that god doesn't exist 100%, atheism is: you don't have evidence, therefore I don't believe you.
When you live in a non-belief, and especially when you are adamant about it, that's when it falls into the class called religion. The only reason why anyone would hate a religion is that he doesn't realize what a religion really is.
However, there is plenty of evidence for the existence of God in the machine nature of the universe. Machines have makers. That is part of the reason so-called atheists often lose their cool when proof for God is shown to them. They realize that their faith in their false religion is slipping, and they don't like it.
Nope, it's just living your life not accepting idiotic claims without evidence. These idiotic claims are everywhere, from ghosts and other paranormal invented creatures to flat earth. We don't accept those because they are idiotic and there is no evidence for them, we are in a way ''atheists'' regarding those.
