Kids feel pressured to figure themselves out too young, and aren't told they should constant revised their sense of self and who they are all while being bombarded with possible things they might identify as. You can see this with people trying to get their kids to figure out if they are gay, straight, cis, or trans before they are even 10 years old. They are given a weird warped idea of what these things are as they are told they are told things like "when boys like boys or girls like girls then they are gay" and little kids tend to play with their own gender and those are the people they like so they decide they are gay, attach that to their identity, which kids do with everything and healthy adults learn to undo and detach their interests form their identity, get it constantly reinforced and I have met a few people leaving their gay identity behind because it was something they make a decision on before they understood what it meant and felt pressured to stick to it. Similarly this happens with gender nonconforming kids being told they are trans when no, little Sally is just a tomgirl, and Billy just likes horses, but the troons are the biggest advocates for strict gender conformity, some of which I think is projections.
