While that seems to work, the fact they shun the apostate more than the non-believer hurts that. They know the de-transitioner will be shunned, and even somewhere in their narcissistic brain there's one synapse somewhere that knows they traded everyone from their own life for this and might, possibly, have an inkling they aren't going to be welcomed back with open arms by those people- and so it becomes "you won't get ANY attention. From anyone. You'll have lost everybody in your life and have little to no hope of finding anyone else to give you attention."
