All stories have value. This one particularly so because of its historical impact. I think you were trying to say that it has no net positive value, which is an opinion that you are free to hold. I suppose thinking people who disagree with you are stupid/crazy is also an opinion you are free to hold, but it's not very logical, reasonable, or productive.
Suggesting that it has no value is not only disingenuous, it is willfully ignorant. You cannot possibly believe that to be a true statement, other than by convincing yourself of its truth through decision. More than a billion people believe in that story. Most of them don't go around murdering people because the voice in the sky told them to. Clearly it has a value, and just because you do not see it does not mean it's there.
