Is gnostic atheism ironic?

[Gilgamesh]

I am not one hundred percent knowledgeable that unicorns do not exist

Just as I know that unicorns do not exist, I can state with the same certainty that I know god does not exist.

But that certainty isn't 100%, thus you don't know.

'Know'

1. Be aware of through observation, inquiry, or information.
2. Have knowledge or information concerning.

You can have a level of certainty that any given god claim is false, and that level of certainty can be high, but you can't know.

Personally, my level of certainty that any given god claim is false is about to the point where I wouldn't give any more concern to a god claim (separate from anything else that goes along with that claim) than I would to the claim that they left the toilet seat up.
