I believe the WT is not right because they write about something that is proven in science. It was not the WT who said as the first the earth is round. Smoking was bad before WT prohibited it. The WT did not write the bible (some added words maybe).
There is actually nothing positive that can be credited to the WT. All they have done is using what somewhere was already written and published that in their publications. I have never read a good news article in which a JW played a role, nor any invention, nor any prediction, nor anything else. If WT would rule the world, women would have no rights, we would still be in the stone age with few men ruling all.
