I have to admit I started watching this show purely to be entertained by people taking "Let's Pretend" too far. But once you get past the content of their beliefs, it looks like each person has built their identity around not just the beliefs but their group of like-minded individuals. And in a way these are like religions having beliefs, behaviors (or rituals) and a sense of belonging to a group. And while at first it seems like the tension in their lives comes primarily from having a parent who doesn't share their belief, later episodes revolve around the problems of leadership of such a group, ie, stepping down or starting one up. The therapists don't try to talk them out of their beliefs but help them find balance or accept adult responsibilities or make concrete steps to improve or stabilize their lives outside the group. It's fascinating in an anthropological way.
