Hi Schnell,
Now that I am around JWs again (after a 10+ year break) I notice the same thing. They all seem to have absolutely no idea what is going on in the real world. I can only speculate (after being at some meetings and seeing how dumbed-down the content is) that none of them are paying any attention to the news or current events.
Funny, growing up as a JW we were encouraged to watch the news, etc., to know what was going on and to have something to talk about at the door.
Now, it seems they are being isolated from the "world" all the more, and so many of them just go along with it. If you factor in the fact that many have no higher education or technical job skills, so are self-employed in service-type work (cleaning, etc.) they really have no exposure to the wider world.
Of course, they cooperate in their own isolation. But the ignorance of what goes on in the real world is astounding.
