No crackpot is doing miracles. Some crackpots are claiming a hanky that some con man hawked to the church is the shroud of the son of God. Another crackpot is claiming that the one test of the shroud that was done, which is probably the ONLY test that will ever be done, was wrong because someone managed to find the "wrong threads."
Somehow that's supposed to make this fake relic special enough to care about it. I can understand caring about it as an historic relic, because it's an interesting story. My apologies to ditter for including him in the group that thinks it's some sort of holy hanky. The hanky won't prove the divinity of Christ. And it's not a hanky that even has any reliable history of doing anything miraculous of its own. You can believe what you want (billions do) but that hanky is a fake and the only scientific proof you're ever gonna get says so.
Let's just say it's quite telling that you insist on calling a 16-foot-long cloth used as a burial shroud a hanky. You can't be satisfied with simply denying that it is the burial shroud of Jesus. Whoever's blood is on it, whatever the source of the image so strikingly similar to the suffering of Jesus, your description of a burial shroud of any nature as a "hanky" is perverse. Whether natural or crafted, it is the image of our savior, and it is shocking that you would call any burial shroud, let alone one bearing the image of our savior, something you would blow your snot into. It suggests a deep-seated, repressed rage and hatred. (And don't bother denying it: the meaning of "repressed" is that you don't feel it; instead take a good hard look at the way you must be coming across to people right about now.)
Were believers of the shroud inclined to rely on ad-hominem attacks as you are, you're failure to have any self-control whatsoever would make a splendid basis for such an ad-hominem attack. Fortunately for your position, we will regularly admit that most skeptics probably show infinitely more composure than you are showing.
You've obviously devoted several minutes to studying the Shroud so, as an expert, I'd appreciate it if you could explain to me how the forger matched the blood type (AB) on the Shroud to the Sudarium of Oviedo and the Eucharistic Miracle of Lanciano, considering that type AB blood occurs in 3% of the population, and that a medieval forger did not know of the existence of blood types.
And while you're at it, maybe you could explain to us how the medieval forger created his forgery?
