Does stating your belief either for or against a deity matter?
Matter to whom? To most people No. To some people Yes.
It makes no difference at all because no one can define or understand the proposed deity. That’s why I don’t do it. The most reasonable response to the staggering implications of existence is not belief or disbelief, but sheer wonder and reverence.
But it makes sense to point out the silliness of literal interpretations of God as described in the Bible.
