Welcome Crolson, I think you can see from the replies especially from those who were JWs, that they are indeed are hurt by their experience.Perhaps the 'beliefs' are not the reason for this because they are simply a variation on ordinary evangelist dogma.
JW teaching is essentially derived from 19th century Adventism and modified by CT Russell in the 1870s who started the Watchtower magazine to proclaim his personal and futile viewpoint on a second coming of Christ.
Through unsavoury power struggles at the top, the leadership has been trying ever since to give some credence to Russell's adventism (though they never use that word). The second coming ideas have been shuffled forward after each time the expectation of advent arrives and fails. It is only held together by threats of punishment namely death at Armageddon and shunning and by appeal to strict loyalty from the individuals to "God's organisation"... in reality to the governing body of Jehovah's Witnesses. The incentive propagandised by them is for the purpose of receiving God's blessing in paradise alongside the unending claim (one hundred and thirty six years of it so far!) that Armageddon is just around the corner.
What has made the difference to us ex-JWs here is the realisation of having been grossly misled under the oppressive mind control of the governing body of Jehovah’s Witnesses. It conforms to every description of what a cult is... which means that it is a cult, a shabby doomsday cult.
