This isn't the real issue though, even if he's right. For the real issue concerns concrete claims like a virgin birthed son of a god. Those kinds of claims require objective evidence for them, since they're extraordinary claims of the highest order concerning events that are impossible to occur on their own within the natural world, based on everything we know about how the world works. So it doesn't matter if there's a point at which objective and subjective claims converge, even though I doubt that they do. Sure, I would see no reason to doubt Win's claim of pain since it's not an extraordinary one. But I cannot objectively feel his pain either. So I would have no way to conclusively test whether he's lying, without some objective evidence coming from a heart monitor or brain scan.
The real reason Win is addressing such a question is because there's no objective evidence for any of the miracle assertions in the Bible. Sorry if that's the case Win, but that's the case. Sorry if it ends your philosophical discussion Win, but it ends it. It could have turned out differently if there was a god who had the foresight to provide objective evidence for biblical miracles, Win. But your god didn't do that.
