MaryJo -- very well said! And, in my observations, that appears to be the main difference between "gnostic atheists" and "agnostic atheists."

GNOSTIC ATHEISTS -- "Belief in any god(s) is ludicrous and defies reason, so I'm going to attempt to socially-shame everyone who believes in any form of creationism or mild agnosticism."

AGNOSTIC ATHEISTS -- "I personally don't believe the existence of god(s) or the supernatural are very likely, but I don't judge those who believe in it; 'live and let live,’ as long as you aren't harming others or trying to indoctrinate them."
