It is sticky on the inside. Disenchanted Mormons have great difficulty leaving the Mormon church. They get stuck. Their questions and doubts are answered in doublespeak. They are told they are Christian, so there is no point in looking for answers there. They are told that if they are struggling or have doubts, it is because of their own unworthiness.
It is rubbery on the outside. When Christians attempt to witness the truth of God's Word they find the doublespeak and Mormonese definition of biblical terms bounce their words back.
This is the plight of Mormons.
