"they have single handily produce more atheist than any others"..
You might have a valid point their JM
JW`s love to point out they are the only ones who witness door to door.Which is not wholly true.
They think they are conducting such a great witness in the world which has also shown to be false.
How do they think the Catholics and the rest of Christendom have reached the numbers they have if it was not for "witnessing "?
How do they think Muslims gained so many if it wasnt for witnessing ?
And the same goes for any other religious belief "witnessing" in one form or another is what has contributed to their growth .
To focus on one sole form of witnessing is pedantic.
