"Jehovah's Witnesses have the most Multilingual speakers of Any Organization in the World!"
It's one of those statements that JW's would think just must be true.
On the surface, it's really unverifiable. But logically, people in Africa and Europe tend to speak more than one language, and JW's are such a minority. Logically, the Catholic Church or some Asian group would beat them out for the title.
The claim just seems to bolster their idea that only "THEY" are doing a worldwide work. We know they are not really working at all in Muslim countries and in most Asian lands. Even the Mormons are working harder to penetrate such areas than JW's are.
