The idea that people believe a certain way because they have failed to examine their viewpoint is naïve. It is simply fallacious reasoning. Do you think this is because you do not understand the atheistic viewpoint?
I don't think that at all. I know that many atheists have not examined their views, because they always have a ready made response from the four horsemen when a religious person approaches them. Some of them always respond with insults and 'woo woo' statements, and this is the mind of a mocker- not a thinker. I don't mean to imply all atheists are thoughtless. I have encountered many of them though that shrug off any other view with what I just said. Mockery and contempt. That is ignorance by one of it's most basic definitions. To outright dismiss what you don't understand, or don't want to try to understand.
That isn't getting into when you ask strong atheists about why they accept scientific materialism alone as valid, or why they think there is good and bad, and how they determine the processes they believe generates emotions is more meaningful than magnetism. Then they divert into gas-lighting, pummeling you with endless questions in attempt to slither out, or they admit it's their personal preference. Honestly, can there be a worse justification for anything than that? A serial killer's preference is killing and they find it enjoyable, so they claim.
It is these atheists I think have not thought about their views much at all. What I am here describing. I think philosophical atheists like humanists do better, but those are becoming less and less over time. I understand why that is, but it would be taking the conversation another way. I understand why humanism is dying though.
Another question one might ask is what made atheists reject all religions, just because they concluded Christianity doesn't work for them? You can't tell me they made a reasoned and thought out decision if they simply jumped from Christianity to atheism. That's actually a simple-minded person, thinking their parents were supposed to be the authority on everything- and they let them down.
