LOL, here we go with Breezy's tautological inexactitudes. You do love word games.
When I claim to an atheist it is the absence of belief in a god or gods. One cannot question an absence.
Should I make claims for historical events I question my proofs. New evidence comes to light all the time, especially in archaeology and palaeontology. I spend an inordinate amount of time in research and double check so that I have the citations to hand.
Sometimes the interpretations of the events have changed because of new or extra evidence to discount the previous theory.
That is what having a questioning mind is about.
Regarding religion, specifically christianity; In my teens, I commenced a 15 year journey of discovery, spent times with people who became my friends for example, Greek Orthodox Priest, RC priest on the marriage tribunal who taught me origin of "Mary Mary quite contrary" and the savage game of croquet, I spent times in Benedictine Monasteries on retreat where I met probably the "holiest" person on this earth. I read the histories, the gospels, all of them including Thomas and the surviving fragments of Mary and Judas. I read the history of christianity in all its gore and inhumanity. I discussed anthropology and the origins of faith with Professor Evans-Pritchard. All the time I was questioning my assumptions and inhaling the opposite view to my conclusions. I travelled the globe.
All the "faithful" with only one exception are terrified of questioning their assumptions and are rigid. New evidence is a threat to their established belief..
Nowadays I question myself every day in my writing and my presence on this forum, without questioning, the basis for my conclusions regarding the non existence of a deity or deities, I am but one of the faithful followers of an "ism"
In my experience the vast majority of atheists are "seekers" and question their own conclusions with the same critical vigour they reject the blindfolded faith of others.

Just a typo

@John 61X Breezy: "I've never been atheist, so I don't know what things are like on that side of the fence."

It's not a fence. It's a book.

Our lives are like books. As we go through childhood, our parents, teachers, preachers, etc., scribble all kinds of stuff on the first few pages of our books. As we become adults and start to write our own pages, we tend to refer back to those early pages for guidance. As an atheist, I made a conscious decision to erase all the stuff about religion from my book, and then I looked around at various religions with the mind of adult. I found nothing worth writing down.

"I've never been atheist, so I don't know what things are like on that side of the fence."

That's easy how do you feel about Thor being fictional? Well that's how I feel about Jesus not being a deity, and all the rest of course. Once you stop trying to square the wheel a whole lot of cognitive dissonance disappears. I'll tell you something else, once you start looking at religious apologetics critically they all unravel fairly quickly.
