The point is, nobody would object to corrections of understanding in itself. Its rather a humble approach, that would even be typical for a genuine searcher of truth.
The society likes to paint themselves this way. However, reality is different, because
1) they never say , something was wrong, now its right, or that they got it wrong the first time, no the call it "refinement" and "new light". Those words are used to cover up what it really was, namely error.
2) they demand absolute obedience to current understanding, they do not allow questioning them or even making your own research. The warning against independent thinking are to be found time and again in their literatur. Disagreement, even if later on may become "new light", is punished with shunning.
3) they claim to be Gods only channel of communication. Such a high claim must stand up to closest scrutiny. Any critisizm should be easily dismissed, and evdence of Gods direction should be clear and overwhelming. The opposite is true, unfortunately.
KJW53, you also said:
I will take my chances at judgement 7 days a week with a religion that made mistakes and corrected them, i would never go to judgement with disunified religions that shove the teachings of Jesus aside and kill one another for a man made word patriotism, Millions upon millions slaughtered, not to mention all of the family lines cut off as well. Not to mention the teachers failing to warn them about the false god worship practices the world added to their holy days. We shall see who satan owns.
It is true, organized religion brought lots of pain to mankind, besides some good things as well. Whether JW are, considering their size, causing as much evil as others, is often a matter of viewpoint. You also can not excuse a thief by saying, well a murderer is much worse. What is wrong is wrong, no matter if big or little.
Also you state the premise, that religions will be judged by God. This is often used by JW. However, God will judge individuals not organizations.
