It is my humble opinion that Article 18 of the I.D.H.R is not well written, it should make it abundantly clear that it is a Human Right to reject all religious thought and practice, to be non-religious and/or an Atheist.
Then two good things would happen, JW Org would have to cease even its devious use of Disfellowshipping, and major trading nations could refuse to trade with those who ignore such a Right.
Note I said " could", usually Greed means they do not do so now, even supplying Armaments and other Technology used in Human Rights abuses, the U.K being a shameful example of this.
But remove the possible "Shunning" from the JW Org's arsenal of weapons and it would help so many to break free.
