I'm a born in, though I don't consider my parents to be "idiots" necessarily. My dad was born in, and doesn't know anything else. My mom converted when she was a teen after her mom started studying. They were both abused as children and I can understand their need for hope. Neither have much for an education, though I don't think they are unintelligent. They have just been manipulated by their own fear clinging to the one thing that feels safe and familiar, the cult. They are very judgemental of everything and everyone and downright cruel at times, but I forgive them anyways. Brainwashing does that sort of thing to people I guess.
As for me, I never really believed. It was just something forced on me. There were many times where I felt terrified of Jehovah and Armageddon, but I never felt like I loved god or had any kind of "relationship" with him. So I wouldn't consider myself an idiot either since I never really fell for anything.
