There are none so closed minded than those who are convinced they have the right answers even without evidence or in the face of contravening evidence. How that is supposed to apply to atheism in isolation, I have no idea.
As it happens, being atheist does nothing for me either. Oh, and science didn't get me here and neither will it get me out. It's totally irrelevant to why I'm atheist. If you want to point the finger, blame theists.
