At the risk of taking your analogy far too literally, how do you propose that these three "blind" individuals would encounter Mormonism?
(Actually we can easily guess what their conclusion would be - Mormonism is manifestation of a severely undeveloped and inadequately evolved society that still requires magic and superstition as a part of its culture.)
I supose for analogy purposes, it would be best if they conducted their examination with their spiritual eyes.
If two roads diverged in the Sacred Grove, one leading back to Palmyra and the other to a rather large rabbit hole, should we not take the path less traveled and lead the life less ordinary? The blind men were already taking that road with their desert journey. When they encounted objects on their journey, their most satisfying explanation was the one which best suited them.
