Every opinion I ever hear about atheism is from non-atheists - and they are invariably laced with profound condescension and reductionism.
Without getting into the question of who is right and whether or not they can prove it, I don’t think it’s a stretch to say that neither the believers or the non-believers have any clue about each other’s true character, nor do either have any business speaking on behalf of the other.
Here, I will tip my hat to the non-believers, for they do a far better job of staying in their lane.
The non-believers I know (and that includes myself) are at peace with not knowing things beyond the reach of science, but know that there is a vast universe of mysteries - they are humbled by the vastness of unknown wonders, and open and eager to learn about them should that ever become possible.
That self-description of one atheist’s state of mind may not 100% apply to every atheist - but I’d venture to say that it is a whole lot closer to the mark than the reductive and condescending descriptions typically offered by religious believers.
Yeah, atheists would never use condescending terms like "sky daddy" and "flying spaghetti monster".
