An atheist can be the same. He too can be very religious in his sentiments. "I am scientific, you are not capable of being like me".
How is that being religious? That's being arrogant.
Many atheists also pretend to be highly educated in theology.
I would argue that one cannot be formally educated in theology at all. Believers can't agree what their scripture mean, which tells me that they mean nothing definite at all. They mean what the reader brings to them as with poetry, and for the same reason - vague language open to private interpretation. Scripture is a verbal Rorschach test. What is there to teach or learn that isn't subjective opinion?
Just because something can be studied doesn't make familiarity with it learning on par with what goes on in academic institutions. We could do a thesis on Disney princesses, but is that really learning? Not unless we make it academic, perhaps by contrasting the white ones (Snow White, Cinderella, Aurora, Ariel, Belle) with those of color (Mulan, Jasmine, Tiana, Pocahontas) to try to glean some social significance that the trends in these characters reveal about changing social mores, it's nothing but fluff.
Theology is similar. How many tiers of angels are there, and what are their various powers and jobs? Which day is the Sabbath? Shall we pray to saints or not? How can one be educated in any of that?
The thing is there are those who claim to be Atheists who are also so religious and fits the bill you have developed up there perfectly.
I disagree.
What he said was, "There's no objective standards in religion. Two religious people, even in the same denomination, may well have different interpretations and attitudes towards anything from Scripture to history to an image of God" and "Once one has separated their beliefs and worldview from evidence and reason, one could believe almost anything."
What atheists fit that bill, and what makes having an empiricist epistemology religious?
Most of the atheists I am familiar with are secular humanists, which is not only not a religion, but is antithetical to dogmatic pronouncements and unsubstantiated claims.
They are also usually pretty well educated, they are evidence based thinkers with rational defenses for their beliefs, and unlike the religious, they are in general agreement about what is true about our common world. The universe is expanding. Life evolves, Tectonic plates wander throwing up mountain ranges and causing earthquakes and volcanoes.
So unlike religious faith-based thinkers, they can't "believe almost anything." Their beliefs have to map a portion of external reality, which is demonstrated by comparing those beliefs to external reality, the only arbiter of what is true and real, and which keeps those beliefs similar from observer to observer. This is why there are countless gods in human history, but only one periodic chart of the elements.
Being religious as the term is used in the West is nothing like that. Being religious is about believing magical things by faith, receiving instruction through people claiming to channel a god, concepts like sin and the sacred, meaningful rituals and symbols, etc..
Atheism has none of that. It is the rejection of that.
