"Those are only characterizations of their POV."
Sorry, gotta call BS on that one. Those were not characterizations of the POV's of atheists, those were nasty characterizations of atheists themselves.
In my humble opinion, attempting to demonize, belittle, and otherwise cast as evil another human being or human beings based solely on your disagreement with their lack of religious belief is an attempt to dehumanize.
Aside from which, touting one's own moral superiority by contrast (as this article does) is just inherently ridiculous and annoying.
