While atheism disavows the existence of a god (or gods) or any form of supreme being it doesn't, necessarily reject religion.
Dictionary.com includes a definition for religion as "the body of persons adhering to a particular set of beliefs and practices: a world council of religions."
while this does not, according to
Dictionary, necessarily command a belief in a supreme being, it is generally understood that if you are religious (in the most common sense) you believe in the power of a supreme being.
According to Reference.com, "Buddhism is often described as a religion and a collection of various philosophies, based initially on the teachings of Siddhartha Gautama, known as Gautama Buddha. To many, however, Buddhism is not a religion, nor a philosophy or a set of doctrines, but rather teachings to guide one to directly experiencing reality. Buddhism is also known as Buddha Dharma or Dhamma, which means roughly the "teachings of the Awakened One" in Sanskrit and Pali, languages of ancient Buddhist texts. Buddhism began around 5th century BCE with the teachings of Siddhartha Gautama, who was born in what is now Nepal and taught primarily in northern India, and is hereafter referred to as 'the Buddha'."
Taoism, for example, is considered (more) a "quasi-religion".
Subscribers to Bahá'í refer to their belief system as a "faith"
If we give that a religion doesn't necessarily need a supreme being to, in fact, be a religion; then any person who subscribes to these godless (read as explanatory - not derogatory) religions must, then, be agnostic - not atheistic.
With all this said, I see, personally, no conflict in an atheist writing about god. Let's face it, Rowling wrote about a wizard ... then made this fictional character, after the fact, gay. She believes in the money get gets from her work - not wizards. Then there's the Blob. I suspect nobody believes the "blob" actually exists - but there certainly was a movie about it. So?
All this says, is that parents should be vigilant about what they allow their children to see. If you believe, don't send your kids. If you don't believe - what's the diff?
It's useful, at least, to have posts like this as it brings awareness to readers but, certainly, as Fossten stated in reference to a stated opinion, "That's your opinion."
If this comment, "As one of the novel's pagan characters puts it, 'Every church is the same: control, destroy, obliterate every good feeling.'" is accurate (not having, nor intending, to see the film) it clearly discredits the author's knowledge-base anyhow.
Opinions are useful but I'm afraid that's all there is here - just opinions.
This is just my
opinion
