I came away from this thinking that the man in the video just did exactly what JW's do to everyone else... on any given weekend......
...rudely invade your space; interrupt their day to tell them they have to agree with them or they look stupid. or worse, will die.
It would have been twice as effective to meekly stand, turn around and sheepishly ask if you could ask some questions.....for example: "Last time I came to this, they said we were in the last days, that people would never die....how did that change.....I need help?? I know 1914 is the key date, but that was over 100 years ago.....did I confuse that message?"
Being a goofball isn't going to make anyone THINK
