As an outsider, I enjoy the topic.
More than 80% of the world's Christians belong to denominations that accept the Trinity. This equals at least tens of millions of people.
This means, should Jesus be an actual person, alive in Heaven, he's cool with 80% of the people professing belief in Him having the doctrine. If he's not OK with it, then he is admittedly a horrible communicator. It's certainly within his power to clear things up, especially IF the doctrine is important. Surely the hundreds of millions of Catholics would jettison the doctrine, if they knew he didnt' like it?
The possibilities are endless, including the Fundamentalist view that correct belief is of the utmost importance and those with the wrong view of the Diety of Christ are headed for Hell (however conceived). It's possible that as the JWs teach, only a select few people alive today (just as in the days of Noah) will be saved, because they alone have proper worship. Or, perhaps Jesus couldn't care less if people think he's God the Son, so long as they're good to their neighbors.
Complicating the matter even further, I've discovered, many JWs only know what the WT told them about the doctrine. This means that cannot refute the actual doctrine, even if they don't believe it. They can refute the WT strawman, but they probably have no idea what a Presbyterian actually believes.
To those of us on the outside, the argument is as pointless as the arguments between Shia and Sunni Muslims over the minutia of theology.
