heh, lies, all lies!
#1 they constantly change doctrines and try to hide behind Proverbs 4:19. i.e. there was the romans 13 light where russell believed in the higher powers to be secular government, then rutherford changed it and said that the higher powers were god and jesus, then franz changed it back where it was secular govt (jehovah was just shizzin with us according to them to see who would stay faithful to his organization =P)
#2 the UN-NGO scandal. anybody that knows anything about politics at all knows how much power one can gain by being part of the UN. You have major hookups with a lot of big politicians, you have a lot of say in whatever country they exist in, and you have a lot of power for distributing. They tried to cover it up by saying they wanted a library card to one of the UN depositories (sp) which everyone knows is a bunch of BS because there's too much paperwork to get just a library card.....
#3 They lie about 1914 because they have so much invested in that time. When they finally got that time stable (in the mid 1940's) they put the faithful and discreet slave, the annointed, jesus' 2nd coming and everything on that exact date....which has already been proven false, but they will just call the rest of the world liars because they are like a kid that can't be proven wrong.
#4 Their rules. They use a lot of OT rules which equals Mosaic Law. They continually say that we are out of the Old Covenant (mosaic law) because of Jesus' ransom, but they still enforce Old Covenant rules, such as blood and sex. They also 1/2 way enforce Old Covenant rules like adultery. For example, in Mosaic Law the person that was guilty of committing adultery was actually put to death.
There's just so many insane things. If you ever run into an elder from one of their congregations, ask them to explain the Pharisee's to you and see what they are about. Keep in mind that JW's exert rules and control over their people to keep them obediant to an organization (which isn't religious love at all). There's a lot more thats messed up, but i'm sure everyone will share =D
