I never really knew any until recently. As a Witness we all thought they were weird. But the two faiths are a lot alike, except the Mormons are really so much nicer than the JWs!
My fiancée was raised Mormon. She stopped attending 20 years ago.
Here is why I think they are nicer then the Johos.
1. Mormons go door to door. So do the JWs. The difference is they only have to do it for two years. The witnesses their whole lives.
2. Mormons believe that god is coming back to rule in peace.The JWs believe god is coming to rule in peace too but he after he kills off 95% of the Earths population.
3. If you leave the Mormons (like my fiancée did many years ago) no big deal. They will still talk to you, still love you. She is very close with all her family. No Judgment! We moved her out of her house a year ago and they sent two brothers to help. They have given her tons of food for her and her three sons, over the years. She even knows nonmembers who have gotten food and support! Well, you know how the witnesses will treat you. Nothing even close!
4. Mormons love their families no matter what, with no judgment. JWs love their families as long as they are in good standing. Even then the will be judging you every minute!
So if the scriptures are true that "by their love you will recognize them" then who knows, the witnesses might be in for a big surprise one day.
