My previous addition to the Jehovah's Witness Wikipedia article was removed, but it has been re-added by someone else, and worded more strongly:
* Belief that a "Great Crowd" of Jehovah's Witnesses is now living that will survive the coming battle of Armageddon and have the prospect of living forever on an earthly paradise. (Revelation 7:9-17) Belief that all others (non-Jehovah's Witnesses) on Earth will be killed by Jehovah at Armageddon, including small children and babies.
Also, my previous addition about JW's being the only christians was modified by someone else to water it down. I still don't think it's quite accurate:
* Belief that only persons who are associated with Jehovah's Witnesses can correctly be called true Christians.
And, I added one more:
* Belief that baptised Jehovah's Witnesses who disagree with official doctrine are to be labeled apostate, be disfellowshipped, and subsequently be shunned by all Jehovah's Witnesses, even family members.
Here's the article for those who are interested: http://en.wikipedia.org/wiki/Jehovah%27s_Witness
