I believe one of the major problems with the WTBTS is its non-transparent nature concerning its beginnings and this has been kept from hidden from those who become JWs.
Another problem has been its unwillingness to REALLY be different from the rest of Christendom in pushing false images and portrayals of Adam, Eve, Angels, Jesus, The Prophets, The Apostles and others as White people. If such persons have never been seen, then they should not be portrayed in any race among the human family. Besides, Christ is NOT flesh and blood anymore. He ascended and is invisible at present.
The WTBTS is stingy with regards providing help and support for youths (especially minority youth). While the WTBTS spends millions purchasing and acquiring real estate, it does very little for those members in dire need financially.
The Governing Body is NOT racially representative of its membership and that tradition is being tightly maintained.
The "Organization" and "The Bible" has more prominence than Christ. Don't believe me! Check out the official website of JWs and count the number of times "The Bible" is mentioned as opposed to Christ. There is a link that says "Bible Teachings." My God! I did not know that the Bible was a Teacher. I thought "Christ" was our Teacher. One would think that the link would say "Christs Teachings." Yet, it is a book that is given more props than our ONLY Teacher.
The WTBTS has lied about the origin the 1914 teaching. It did not originate with the WTBTS. It actually came from another religious movement called The Second Adventist. A movement Charles Taze Russell was a member of and even a contributing editor of its magazine. When he broke away from that movement, he "borrowed" that teaching. So was the Second Adventist Movement back then "a" or "the' Faithful and Discreet Slave?
Charles Taze Russell had many writings, yet none of them are made available to JWs. Why? Because Charles Taze Russell would sound like an apostate by Watch Tower definition today.
The organization hails itself as "the truth" and those within it are "in the truth." This is blasphemous because Christ is the truth, not an organization.
The Most High God will deal with the "voices" not doing his will and teaching the truth. As the Pharisee Gamaliel said at Acts 5:38-39:
I say to YOU, Do not meddle with these men, but let them alone; (because, if this scheme or this work is from men, it will be overthrown; but if it is from God, YOU will not be able to overthrow them;) otherwise, YOU may perhaps be found fighters actually against God.
Yet, the WTBTS and ALL religious organizations claiming to speak as from God are to be tested. The problem is that the WTBTS feels that it is above such examination. (1 John 4:1)
Thus far, it and ALL religious organizations on earth have failed the test of truthfulness. NONE have listened to Christ as The Most High God commanded at Luke 9:35.
They listen to OTHER things such as books and organizations rather than the living Son of God who is able to teach us without the use of books men themselves make holy.
