Really? You fail to see anything wrong from the story from every perspective?
You don't see how people who are not religious (Jewish) may find the story elitist? Potentially insensitive?
You may view it as one individual (as I do), but posts (and indeed all things in life) are not made and done in a vacuum. The fact of the matter is there were 239 people who perished on a plane which has not even yet been found. 239 people who did not have Shabbas to save them.* 239 people who likely will never see their families again.
Ever turn on the TV on a Sunday? See an evangelical preacher saying that he blessed a paralyzed person who is now able to walk after drinking some holy water? How much credence do you put in that? I'd venture to say, as a religious Jew (as I think you may be), that you don't give it much and that you'd simply dismiss it out of hand, calling the guy hokey. Why is this different?
I can only ever see things through my perspective, which is that of an orthodox Jew. However my worldview is based upon not only my beliefs. It also is based upon the accumulated knowledge of thousands of Rabbonim of spiritual and intellectual genius, my belief in them, the depth that my personal intellect can grasp, and my personal experiences, as well as the culture I was brought up in. These aren't listed in order of importance, as they are all intertwined and linked and knotted together.
So therefore, adressing your last point, if I think that holy water curing somebody isn't the truth- it's not the same thing. It's different.
I don't see the story as elitist, at all. G-d rewards good deeds. The story would be just the same if it would be a Mitzva that non-religious people have an easier time understanding. Let say, the plane was leaving on Sunday and Andy missed it because he decided to attend a charity function instead. Would that be considered elitist?
I think people are mistakenly extrapolating from the story the following non-fact: the other peole suffered the terrible fate they did because they weren't Shomer Shabbos. The story is about 1 individual. That's all. It's not pronouncing judgement or explaining why the other people died. It's about one person being rewarded by G-d for some good deed that he did (does that mean that the other 239 people never did any good deeds? NO!). Can it be that he merited being saved because of Shabbos?
It may very well be.
