I liked to ask JW's "when you research purchasing a new car, stereo,phone ect. what do you do?"
If you want to buy say a Ford focus car you don't use Ford's information exclusively to decide if it's a good car.
You find unbiased, neutral, unrelated reviews and information on the car.
So what do you do when you buy into the most influential thing in your life, religion?
Careful what you wish for Watchtower.
