At this point in the indoctrination, it could possibly be viewed as “apostate” and from his viewpoint, the worst thing that possibly could be forwarded to him. An Al Qaeda video might get better reception from an indoctrinated JW. I suspect your son would balk at each point and say, “We aren’t trying to convert people…it’s a choice…you can use your own Bible…we read the Bible in context.” And on some level, he would mean it. This series is strictly for non-JWs and those early on in their study.
Of course, every now and then, a JW might go through a person of questioning or curiosity, and take a peek at what is out there. In that case, I believe it’s important that what they find doesn’t scare them away.
I know myself having accidently stumbled upon some websites in the past, all black with flames and crazy allegations about conspiracies. It basically scared me back to the fold.
Even when I was waking up, I was disinclined to trust even the most factual information out there, sites like JWFacts. I assumed from the start these sights contained lies, half-truths, and misrepresentations. Over time, I realized sites like JWFacts were 100% truthful, but it was an uphill battle.
Addenum:
I’m not sure if born-in vs convert may make a difference. In a poll, 2 out of 3 who were raised a JW no longer identify as such.
Not every study converts. In fact, very few do. Somewhere along the way, most drop off, either because on not accepting teachings from the get-go, or the JW lifestyle being too intense and they do not want to radically alter their life (no holidays, door to door, ect). However, for the few that clear these hurdles, they are truly hooked.
Just look at members of other cults, like Scientology. Many of them, like Tom Cruise, are converts.
