There will be appeals. This is ludicrous. Next will it be unconstitutional to wear a religious symbol openly on your neck while walking on a public sidewalk?
There cases in Europe when it was argued whether a cross on the neck is permissible as ornamental jewelry or still too offensive. The question whether a crucifix worn for the purpose of identification with Christ is offensive: everyone understood that it would be. The setting was hospitals and perhaps schools, and in one case a TV anchorwoman attire.
Soon, very soon, your prediction will come true.
