The title is not striking, I still am non the wise to what the book is about. That is my way of constructive criticism.
Whenever you attack the JWs, you will be attacked for it. These people are brainwashed, deceived and most are unwilling to hear truth. When you tell someone who is deceived that they are "wrong", or "false", it grieves them inside. When you present the truth to those who are living in a bubble, they don't want to leave the bubble, but rather shout from inside the bubble telling you that you are wrong... Even though they cannot defend what you are showing them.
The JWs think that when you are showing them their own errors, they are being persecuted, but on the contrary, they don't understand the difference between persecution and exposing them for false teachers, Deceivers and wolves in sheep's clothing.
I get hate mail a lot for preaching against them, it's just normal. You may wake up some, or you may just antagonise them further to remain in their bubble.. at the end of the day, you can only sow the seed and see how it grows.
