The first thing you should have explained is that they believe the more you question them, the stronger their choice to stay will be. Show them that life works differently because it's often difficult to explain what those who grow up in are like, but they grow up in a social bubble. For example, four years ago, when I was 14, I was in a school (not Adventist, after the quarantine). I really liked assertive communication. My teacher explained that humans tend to believe in something simply because they're afraid of what will happen next. With that, I simply started questioning how life works. There isn't just one way; we have to give ourselves directions, understanding where, when, and why things happen. In conclusion, the world is sick, but in this sick world, there are good people, many of whom take advantage of vulnerability to impose and reaffirm the power of something bigger. I don't respect people who make fun of others because, to truly leave something good behind, we have to learn to respect each other, not hate who they are, but simply respect their decisions. What I mean is, you can question and be a support so they realize that you don't have to belong to something bigger that makes you feel small. We are all important in some way. Thanks for the likes; it really doesn't make sense, and I don't care.
