One thought ... sending a letter of dissociation is one way of halting any where are you calls, we haven't seen you recently at the meetings.
If I were to send in a letter I would state that after an honest review of the doctrines which were created and promoted by the WTS leaders (GB) ie. 1914 I found that these doctrines were not inline to what the bible says or what Jesus said in preaching his new Kingdom order, in fact I find them sinful, unfaithful and apostate in nature.
I made a baptismal personal vow of loyalty and faithfulness to Jesus, not to be faithfully loyal in servitude to the propagating sins of men or sharing of those identifying sculptural sins.
To me being righteous in the eyes of god means to be loyal and obedient to his directions and will, not to sinful disobedient unloyal men in spite of them proclaiming themselves the FDSL.
