I agree that they will survive unless the government starts investigating their pattern of child abuse, their tax exempt status, and their violation of UN human rights.
Noting the aforemention points, they are coming down hard on the younger generation trying to indoctrinate them as early as possible. The younger the mind, the easier it is to mold. The hell with what the Bible says, just as long as they are able to be indoctrinated (mind controlled), baptized (enslaved), good member (trapped).
They love to have entire families join so the bond is that much tighter and by the time they try to leave, too much to lose.
