And... so?
Wherever you think this means that "the vocabulary used" invalidates the experiences quantified by the paper, you are wrong.
Everything is described through cultural linguistic constructs. That's irrelevant to the reality of any given experience, and if your assertion as to what the sentence implies were what it in fact implied, there would be no reason to continue with the presentation of the study. Since they did in fact continue, we can fairly conclude that this wasn't the assertion--as we can also infer from the absence of your conclusion actually being anywhere in the statement.
See, this is where I feel fundamentally required to respond to the statement not as an argument, not as a perception I consider incorrect, but as an outright deliberate lie. My basis for this is that you could not actually live as long as you have while generally believing what you assert to be true, is true, but rather you apply an entirely different set of criteria to religious concepts as you do every single day to every other subject, and you could not do otherwise.
I'm glad in this case I didn't have to revisit the different commonplace forms of that here, and you, surprisingly, didn't make the claim that because there is an alternate scenario that is also supported by the evidence, it then becomes the case the evidence no longer supports the original interpretation that it in fact supports. As always, for everything, every day, you then have evidence for -both- scenarios. If you find the prime suspect in a bank robbery with a bag of cash with the bank's logo and a gun on his coffee table, noting he has a roommate who could have done it does not make that suddenly not evidence for the prime suspect's culpability. It is simply not, in itself, -proof- (the standard goalpost-shift here to an infinite-regress of expectation, as well as tantamount to demanding forced conversion, proof provided, the requester's choices now irrelevant). Nor is this, because it is -a- line of support (of the particular peer-reviewed sort commonly demanded), therefore the -only- line of support. I could go on at length regarding other lines of support (i.e. improbability of future prediction happening "by chance", historical notations of secular historians, martyrdom of contemporaries, etc.), but this is a waste of time if I don't perceive basic willingness to consider information on the same terms as every other topic in the requester's existence, and as basic reason calls for. Some don't have that. Maybe that's because they're simply lying hypocrites. Maybe you have an alternate explanation.
