Teaching should be done at home where parents should educate children of the dangers aspect of cults.
From my years of growing up and meeting with many different encounters, I sincerely believe that parents can put in a better effort to talk with their children about lives and their encounters. With parents past experiences to convey, I do believe children will understand of what are dangerous and not to be involved with.
It is always important for parents to play a part in their children's lives as they are growing up and learning new things. Parents should act a role as friend to guide.
