This well-within-living memory innovation has already become quite the tired canard…
First problem - Where does one cross over from “agnostic” to “gnostic”?
Where in the spectrum between “I don’t know”, “I’m not sure”, “It’s possible”, “It might be”, “I think so”, “I’m convinced” and “ALLAHU ACKBAR!!!” has one crossed from “agnostic” to “gnostic”?
This obviously segues into discussions on the murky difference between “believing” and “knowing” and how arbitrary those distinctions are (“It’s reasonable to assume…” being a secularist analogue for “I have faith that…”).
Second problem - the creation of the term “agnostic atheist” (which is really the only reason this sophomoric theism-square was created) is nonsensical. It takes a word that claims belief in a lack of gods and mashes it with another that means the existence of gods is unknown if not unknowable. Nonsensical.
Probably why Sagan picked “agnostic” for his religious label…
If you don’t currently believe in the existence of god, but concede that your view is due to a lack of evidence and there could be something yet discovered, there’s already a word for that. A real one;
The classic agnostic.
Another attempt by atheists to widen a net that doesn’t work very well. It still doesn’t.
