I actually remember that talk, but when you're a teen who dropped out of school, with very little life experience, it sounds very authoritative. And when you see tons of adult people clapping like crazy, you say to yourself, surely all these adult people can't be wrong. We as kids depended on adult people to help us navigate our way through life. Little did I realized I was in a group of idiotic adults.
That same thing goes with young jws today, they trust their deceived JW adults.
