Coming my personal experience, every atheist I encounter came off as self-aggrandizing, self-centered, and snobby. They believe that they are smarter and "free from the control of the church" and act like a complete asshole to anyone who is even remotely religious, and this is coming from me, who is not even Christian.

They like to act smart while completely disregarding the academic and technological advancements caused by Christianity and other religious movements, like how Christianity boost literacy rates. It's stunning on how these dumbasses claim to be smart but are actually not.

Can someone please tell me why I keep encountering these types of atheists?
