These generalizations that you make about atheists basing on how messed up the world is are false. Any complex system will have issues, and you cannot compare it to an imaginary one. People may cry about many things but fact is they still do not express any interest in living in existing religious states. So maybe what you're seeing as a cultural myopia is an otherwise excellent tradeoff. It's easy to criticize any system while taking it for granted and not living in systems you're advocating for.
