SO ! the Org. has finally caught up with me ! I used to do this kind of "ministry" 30 years or so ago. I would be conscientious and move the conversation in to talking about the Bible, which I doubt many J.W's today will bother to do, but I used to prefer to work alone, as I knew other J.W's would frown upon my method. And now it is Official Policy !
I remember one lady I called on, I had called there before, and when the conversation came to a close, she said to me "I don't mind you coming around and talking to me about the Bible, but I can't stand those Jehovah's Witnesses !".
This is great news, as although the Org's intention of keeping J.W's busy, and thinking they are doing something productive will be accomplished, hardly any Converts will be made.
Above you said " you wouldn’t even know they were JWs." I bet I would ! having been "in" for all of those bloody wasted decades, I can spot 'em no trouble.
This is good news though, as again we can clearly see in this the desperation of the Org. to make new converts, and yet everything they are trying will not get any dramatic , or possibly even measurable, results.
J.W Org. is moribund, really "The End" cannot be that many years away, but it will not be the End of the World, but the End of the Org.
I hope I live long enough to see it !
