Isw1961, welcome. As previously said, I hope you are willing and courageous enough to discuss and research what you believe is "present truth," rather than just being a zealous J.W. who feels they can make a few pro-J.W. statements as a "defence of the truth", and then disappear.
If you are sincere, then I'd like to pick up on certain points you make; (I am presently regarded as a J.W. by others)
1) "Even Apostle Paul taught (in 1 Cor. 10:11) that the kingdom would come in the first century. Such false teaching...."
A bit of research shows that Paul was correct - the kingdom (Gr.basileia - kingship) was established in the first century, as Psalm 110:1 and 10 other Greek scriptures confirm! (type in "right hand" in WT CD ROM)
2) But people choose to become JWs knowing very well about the above policy!
Do you personally know of any Bible Studies who were clearly warned about shunning & disfellowshipping as they studied the Bible Teach book? I never had to mention it when I studied with others. Try it - and see how long a study continues!
3) When I found certain things confusing, I brought to the attention of the higher-ups who, in turn, told me to wait for Jehovah.
When you say you found "certain things confusing" do you mean lies? Such lies as, new scrolls, judicial committees, Romans 6:7 is about literal death, the name Jehovah's Witnesses is Bible based, J.W. paedophiles should not be reported to worldly authorities, and Christ won't judge dead people for their past sins, etc., etc. And who are the "higher ups?" Didn't Jesus say that Christians "are all brothers," and that "one is your leader?" Therefore, in the Org's world, only they have the authority to discern truth, and can present falsehoods with impunity.
Try using an online Greek concordance when studying/reading the RNWT. You'll get a clearer understanding of how some scriptures should be translated, rather than how they are presented by individuals who have an agenda to push.
e.g. Hebrews 13:17 - "Be obedient to those who are taking the lead among you and be submissive...." (RNWT)
Literal translation - "Be persuaded by those going before you, and be yielding to admonition."
Much more loving and appealing for Christians, don't you think? Looking forward to hearing your views. (1 Peter 3:15)
