Don’t see many jehovahs witnesses anymore. I never knew this, but the Bible says to slam the door in their faces essentially (in the faces of those peddling false religion). I no longer feel bad shutting the door on them, and don’t bother to even engage them on anything. If they persist in trying to contact someone,, and someone wants to say something to them, tell them ‘you and your false religion are not welcome on my property’and shut the door.
I had a couple of white shirt Mormons come to my rescue once when I broke a bike chain while riding on a greenway. I had no tools, they did and helped me get back to riding.
I managed to thank them and ride off before they started their spiel.
