As a person who looks at language for a living and have come to believe all of what we know and believe comes from a combination of experience, thought and language.
Not matter where we look cultures have religion. We, as human being, like to make religion, as much as we like to make language or literature. We are different to other animals in our ability to do so in such a way.
So I cannot be “against” religion, or language or literature. It is inherent in us to make religion, language, literature and the such.
What I do have believe, though, is that we also have the same capacity to “see through” the need for religion, language, literature, etc. For whatever reason we have religion, language, literature, etc, we have to learn to deal with it as reasoned but critical beings in a physical universe.
