Maybe you could make it a little more personal, like StinkyPantz mentioned.
JW = Cult
What draws one to become a JW?
Lovebombing in your time of need.
Association ONLY from w/i.
You may be able to reach someone that is considering joining. Almost everyone as least knows of a JW, from school or the neighborhood ....
Some scenario's:
1) Do you remember a lazy Sat. morning when you finally had nothing to do and all you wanted to do was sleep late and just laze around? Laying their in your bed half-awake, half asleep - enjoying your tranquility.... suddenly it is shattered by a loud knocking on the door. Aggravated by your peace being interrupted you unwillingly go to the door. A young man and an older woman is standing there, with big smiles on their faces, excited about being able to tell you how to save your life. Offering you two magazines - The Watchtower & the Awake.
RUN - Slam the door in their face and never look back. This little ole' grandma is a member of a religious cult..............
..Ultimately to lead you on your path of Self-DISTRUCTION
3) Imagine back to when you were in Elementary school. It is around Christmas time, everyone is acting silly. School will be out for a couple of weeks, everyone is excited about what they are getting for Christmas. The room is decorated with paper ornaments that the class had been making for over a week. A little tree was at the front of the room with little lights and candy canes on it. Remember how exciting Christmas was back then? Everyone had brought something for the "last day of school" party - The Christmas Party. Some had brought drinks, cookies, cupcakes, chips; everything anyone could want to eat! Everyone had also brought gifts to give to each other. Some wrapped so carefully, others put in a paper bag with a ribbon tied around it. Christmas back then was so much fun...
For everyone, except, the little girl with her long hair in a pony tail sitting in the far back corner of the room. The little girl that could not have a cookie or a chip or a drink or a present. The little girl that did not know how these kids could be so happy about Christmas becasue all of them that celebrated it was going to DIE.....
There are 3 scenario's. I don't know the age/type of people you will be speaking with, so I don't know which direction to go. I had to do a speach in college. I talked of a very powerful man, told of his attributes, his endeavors and his achievements. How hard he struggled to where he eventually ended up. Toward the end of my speech people realized who I had been talking of because of his atrocities. My instructor and my classmates assumed I was speaking of man that had a great accomplishment: maybe President, one said Jesus, one said Martin Luther King and so on. I was speaking of Aldoph Hitler. I ended up with a A on the speech. If it had of been "a nice person" it probably would have been a C.
Just my two cents.
