It takes no mind reading to know that when someone writes that someone else’s faith depends on a piece of cloth it is intended to inflame. The statement is, on its face, insulting. Your tu quoque response further personalizes it.
The thread was about historical evidence regarding historical artifacts. No one said anything about religious belief—not in the Haaretz article, not in the comments before yours. You have been told repeatedly that no one who believes the Shroud is authentic does so because his faith in Christ depends on it.
You have been told this repeatedly. Having been told this, every time you make this comment it is prima facie evidence that you intend to inflame.
