That's not quite it, gnu. I know some Jehovah's Witnesses, and none of them think they are among the 144,000 who to to heaven. They assume they probably are not. What they do think is that many millions of good people (including, hopefully themselves) will remain on the Earth but will live in a new paradise-like planet that has been transformed into a fertile, peaceful environment where both Nature and the human race flourish in natural balance, where there's no more war, one unified society that welcomes all races equally, etc...

So this thing they believe about the 144,000 does not refer to the presumed destiny of most JWs, but just to a small minority of them.

I will say this: Although I do not share the belief system of the JWs, all of them that I have met have been good people, good neighbours, people I felt that I could trust to be good neighbours...and that counts for a lot. This doesn't mean I buy their beliefs, but it does mean I respect them.
