It only exists in relationship to religion. It's mental illness without believers and it cannot understand why that is.
So, do you think atheists can't admit that we wouldn't be atheists without theists?
Of course that is true. If there were no theists, there would be no atheists.
And "without believers" you're probably right - it would take a mental illness to go on and on about something that no one (including yourself) had ever seen, heard, experienced or talked about. But that's not the situation we're looking at in the here and now, are we? Not in the slightest. There certainly
ARE people who claim to have seen/heard/experienced, and they damn sure talk
A LOT about Him/Her/It (god). So is it "mental illness" to seek answers to questions and poke and prod people's ideas for which they have
completely insufficient evidence? Is it mental illness to ask for evidence before venturing into actual belief?
In other words, what you said is completely useless. True... but useless. You want a world without "believers?" So do I. I'm just not deluded/foolish/brainless enough to think that "atheists" would go on discussing "god" and how He probably doesn't exist if there were no one left claiming that He did. The discussion would be over. No believers, nothing to discuss.
