Take your time and carefully read what the Watchtower says about rebellion against their organization.
How many false assumptions are there in the following Watchtower quotes?
'Godly hate is a powerful protection against wrongdoing… Are we doing that? Apostates are included among those who show their hatred of Jehovah by revolting against him. Apostasy is, in reality, a rebellion against Jehovah. Others claim to believe the Bible, but they reject Jehovah’s organization and actively try to hinder its work. ... a Christian must hate those who have inseparably attached themselves to the badness' Watchtower, October 1, 1993, page 19. See more Watchtower quotes on the Apostate Jehovah's Witnesses.
'The slave’s will is Jehovah’s will. Rebellion against the slave is rebellion against God.' Watchtower June 1, 1956 page 346. (Who is the Faithful and Discreet Slave? - See Watchtower June 15, 2009 )
'If a publisher refuses to do this and ignores the prohibition on associating with the disfellowshipped one, that publisher is rebelling against the congregation of Jehovah, and “rebellion is as the sin of witchcraft, and stubbornness is as idolatry and teraphim. … If after sufficient warning the publisher persists in associating with the disfellowshipped person instead of aligning himself with Jehovah’s organization he also should be disfellowshipped.' Watchtower October 1, 1955 page 607.
In the above Watchtower quotes they claim to be God's slave and channel of communication to the entire world. 
On rare occasions the Watchtower has admitted having no divine inspiration and mistakes are possible.
Therefore some or all of what they teach could be incorrect. If mistakes are possible and they have no divine inspiration, then JW's are obeying man, not God. Some or all of what they teach could be contrary to God's will.
Notice how much importance is placed upon the organization. It's almost as if 'the organization' and God are one of the same. Some say the organization's importance could be a modern day form of idolatry
Jehovah's Witnesses believe that salvation belongs to Jehovah. Psalms 3:8. They cannot honor humans in the same way they honor God. That's why they don't celebrate birthdays, Mother's Day, or pledge allegiance to their country and to it's flag
Holding human religious leaders in high regard, being submissive to them, being baptized in the name of their religion, ... appears to be contrary to the strict moral standards JW's live by.
6:35 'But be loving to those who are against you and do them good, and give them your money, not giving up hope, and your reward will be great and you will be the sons of the Most High: for he is kind to evil men, and to those who have hard hearts.' Luke 6:35
6:37 'Be not judges of others, and you will not be judged: do not give punishment to others, and you will not get punishment yourselves: make others free, and you will be made free.' Luke 6:37

Where does the Watchtower's 'spirit-directed' messages come from?
Satan competes with God for our devotion. So does JW.ORG They make it sound like obeying them is exactly the same as obeying God when in fact it is not.
Rebellion against the Watchtower is NOT the same as rebellion against God.
The truth is just the opposite! Jehovah's law requires that we don't serve other gods, images, representations, or symbols of salvation.
For JW's the Watchtower organization has unwittingly become a symbol of salvation, just like the 'ark' in Noah's day!
If you're a JW and want to leave, you won't be leaving God and 'His' organization.
The Watchtower teaches we must know how to hate in order to please God. This is not true! According to God's son Jesus, God does not hate!
Hatred contradicts God's love. Jesus says God is kind to the 'ungrateful and wicked' and we become 'sons of the Most High' when we love our enemies without judgment. Luke 6:27-42
The truth is exactly the opposite of what the Watchtower teaches! We must know how to hate in order to please the opposer of God, - Satan !!!
