I went to my megaTBM parents' house last night. On their fridge was one of the "youthy" posters with an overdone sandcastle with the caption "How firm is your foundation?" or something close. I saw it and had to do a massive eyeroll. The poster really stuck with me. The foundation of mormonism is so "strong" that it withstands about zero contradiction. Mormonism is so full of truth, they hide behind words like "anti" or "apostate". Mormons have such a strong foundation of faith that they have full blown seizures when you question their faith and launch into ad hominem attacks on those that question (we only left to sin, drink, fuck, etc...).
Were mormons to honestly ask themselves how firm their foundation is, there would be no mormons left. Instead, this poster become a piece of propaganda that builds up the walls of crimestop type barriers around the world mormonism needs. The poster is meant to demean all those that do not obey the church and therefore have built their foundation on sand. It is meant to buttress the believer and demean those that have left. It is really a perfect example of mormon mind control tactics.
EDIT:
This is the mormonad:
