I haven't seen a confident, educated person come in from the d2d work in decades.
I have! And it still baffles me... he's very smart (that is, smart smart, not "gee how he done got so learned" JW smart), he's very confident (super outgoing, and he's moderately famous and rich), has a model for a wife who he loves deeply (so he's not doing it for a pretty sister), and yet he still got baptized just a few years ago. This, in an age with Google and Wikipedia and JWFacts and JWN and, and, and.... Like Pickler, I want to ask him, "Why?!?"
Besides that, I've seen one other person convert since 1995 that I can think of, and he was lonely due to his disability, and looking for acceptance.
