I raised my two kids as jws. I reckon the reason they stopped believing(I truly kept my opinions to myself after I woke up) was that they had such mature friends.
Their non witness friends just excepted them as they were, while the witness kids friendship was conditional and may I say rather nasty at times. When they questioned jw beliefs guess who still treated them the same? When they were depressed about their loss of faith, who supported them (of course I did too)?
Those friendships are still strong. That's not to say my kids didn't have disagreements with their non witness friends, it's just that they got over it and moved on as mates.
Actions speak louder than words.
