Ironically, many homeschooled kids in my area turn 18, get a low-paying fast-food-type job, quickly find a 'worldly' boyfriend or girlfriend, and then fade or are DF'ed, never to set foot in a Kingdom Hell ever again.
So not only do they lack any kind of an education and socialization skills they have been indoctrinated with prejudiced views and are frankly lucky if they haven't been sexually, emotionally or physically abused but will loose their families too through shunning.
