Many theists keep trying to judge alternatives ways of thinking based on what they know and experience. They try to make things like people who believe in evolution and value science over the writings in books that they consider sacred, fit the mold of their religious practices.
Many religions preach this black and white mentality (you're going to heaven/you're going to hell, you're good/you're bad, you're in favor of God/you're against God, you're in the right path/you're in a path of self destruction), and therefore, perceive anything that challenges or explains their believes in a different way that way too by labeling things as "Satanic", "Against God", etc. Furthermore, they even attach morality to different ways of thinking, such as the way the WT publicizes that people who challenge their teachings deserve to die and will die.
They argue against atheism as if atheists are an organization or organized entity, as if all atheists are united and believe the exact same thing or have the same set of values. Same thing with that nonsense of "Scientism". It's just another interpretation from some theists, trying to make people who challenge their believes fit a mold and make it into some kind of entity that they can attack, label and place under the "will be destroyed by God" (or its equivalent in their denomination lingo). That way they can continue reinforcing their believes and continue dismissing other people's.
To me, the fact that many (not all, of course) theists continue trying to start arguments over our morals based on what we believe (i.e., according to a person who posted here, we are not supposed to be upset for bad things happening because that's supposed to be part of the evolution process), makes no sense.
I personally dismiss all that as a misguided attempt at making alternatives ways of thinking fit the mold of how they view, perceive and believe things.
