Just a couple little tidbits from me.
You mentioned the good friends you made. When I was disfellowshipped my best friend wrote me a letter explaining that she would have to think of me as a dead person for now. I was so brainwashed that I accepted this. I was the "bad" one for being disfellowshipped so I deserved it right?! nevermind the fact that the brother I was dating was forcing me to do things with him that I didn't want to do (leading to my disfellowshipment). they only love you conditionally, whereas my worldy friends i had made in school forgave me for telling them they were bad association and not talking to them for ages.
Also you mentioned that some of their info seemed to be bibically true... something like that. One of the kickers for me was the verse they use to "explain" the whole 144k thing. If you read Rev.7 in it's entirety iit's talking about 2 classes of people, but not a heavenly and earthly in the sense that the earthly will inhabit the earth. It talks about a heavenly class and a class that will perish. It doesn't back up their claim at all. I'm not sure if I have the scripture right. Look in the back of the bible in that questiion section under the 144,000, then read the verse and all the ones around it.
