I'm critiquing the epistemological flaws in your own position

But that's just it. I don't have a position to critique. I don't have a belief to assert. None.

I'm not claiming to know anything other than the assertion that God exists isn't supported by any demonstrable evidence and therefore not a useful assertion. Its as useful as the flying teapot, which is to say not useful. And often harmful.

I'm failing to see the harm in this position that concerns you.
