Seeking human rights or religious freedoms through the various means this world has to offer is not wrong in itself.
However, considering the WT's historical stance condemning the League of Nations, then the U.N., it is hypocritical for WT to seek help from the very entity it claims is opposed to God's Kingdom.
The WT brings much persecution and scrutiny on itself due to its claims of superiority and provincialism. "Pride come before a fall". If the WT did not publicly condemn all other religions as being false while also condemning every aspect of the system as Satan's world, from which Christians should be neutral and have no involvement with, then when WT appeals through these various governmental agencies no one would think much of it.
But, when WT condemns these organizations, then turns to these very same organizations when it needs help, the hypocrisy is all to apparent- and intolerable.
No one is criticizing other religions for using the UN, OSCE or other entities. Why? Because other religions have not spent the past 70 years condemning them as a tool of Satan, the "image of the Wild Best".
WT's attitude of "wait on Jehovah" suddenly becomes a "theological concept" rather than a pragmatic approach they actually put faith in when their own interests are threatened.
