Do you ever get together and bring up the subject of whether or not the law of gravity is true or not?
Neither do I.
And that's how most Witnesses view their doctrines. There is no discussion to be had, there's nothing to talk about. Here on this forum some spend hours discussing how Witnesses are wrong, which they are, on so many different doctrines. But Witnesses don't analyze the doctrines. They just accept them.
At that Gilead thing last night, no one brought up any doctrines. To a Witness, doing that would be like questioning gravity, what's the point? So we talked about Bethel, and field service, and Gilead, and personalities in the congregation. And funny stories. If anyone had brought up anything at all related to doctrines, everyone would have gotten really nervous. Usually I try to bring something up, last night I didn't, guess I chickened out.
