And that watchtower book thing u hand out has actually helped me in the
past.... Taught me that resentment only hurts me and not the person I
resented
Remember, a lot of the things they might show you, is common knowledge that can be found anywhere. The only difference is that by bringing it to your door, they've made it easy for you to assume they are somehow extraordinarily enlightened and they'll want you to believe this is because they are the only true religion. They believe that soon, anyone who doesn't listen to their message and become a Jehovah's Witness, will be killed by God. They've been preaching that the world is going to end and have been scaring people into joining them for over 100 years.
JW's as individuals are typically nice and well meaning people and come across as respectful and harmless. If they were monsters, people would run from them rather than being taken in by their well rehearsed presentations.The trouble is, they make it appear that they are at your door out of concern for you. They may be concerned for you and others but knocking on people's doors is more about them saving their own skins and not being killed by God for not doing so. They are required to do this and they are required to report how much time they spend in this activity and keep records of who they talk to (such as yourself). Once you get involved with them, you will be expected to buy into their program 100% and build your life around it. If you don't accept what they are teaching or do accept but later change your mind, they'll show their real colors and they aint pretty.
A lot of us here have had our lives devastated by having become involved with Jehovah's Witnesses. It's sort of like the adage in that old song, Hotel California.... where they say, "You can check out anytime you like but you can never leave" (without serious consequences that is).
If you mention that you visited this site, there'll be stern warnings about listening to anyone who was a former JW. Hopefully this will be a red flag for you. They don't want you to investigate them without being in control of what you are finding out about them.
