People are making such massive life decisions based on their perception that the church is true. They're deciding who to marry, when to marry, what to study, how long to study, how many kids to have. And then If they stop believing, their marriage is in jeopardy, they're often ostracized by family and friends. If they're LGBT they may be killing themselves or throwing themselves into a life of sadness and misery because of how their family reacts to their coming out. So the stakes are just incredibly high, not to mention just all of the time and money people dedicate to an enterprise, when now we know that information was systematically withheld from them for decades so that they couldn't make an informed decision.
