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.
^^That.^^
Nearly every J-dub kid I knew growing up being homeschooled from very strict familiies fell in with a really rough crowd (gangs, drug dealers, etc.) in a matter of a few year and ended up getting into drugs or getting pregnant before they were 18.
BTW, why do the keep them out of schools? I suspect 3 reasons (all under the guise of protecting them from worldly influences and bad association):
1. Evolution
2. Pressure to go to college
3. LGBT-friendly environment
4. Their parents hated having to deal with defending their JW beliefs to their classmates growing up and they'd prefer their kids not have to endure it too. "Why no sports/dances/birthdays/holidays/etc......"?
