The scientific verdict is that, if anyone says/posts one word doubting the authenticity of the Shroud (such as saying that Jesus must have glowed in the dark after his death), it proves they're an anti-Catholic.
I am not Catholic but I believe the Shroud to be authentic. Anyone who watched “The Face of Jesus” on the History Channel recently could not come to any other conclusion. The scientific evidence presented on that program was overwhelming in verifying its authenticity.
You seem to be trolling to start the argument you’re complaining about.
