Yes, I was 15 when I was "baptized" in the name of the Org. Back then, I had no internet and no means of refuting what I was taught. And I likely could not have explained key teachings like 1914 or 1919. It is definitely not an informed decision.
Even before that, I became an "unbaptized publisher" at 8. I don't even remember making that "decision". It just sort of happened.
