I get your point goneforgone but as far as the JW machine is concerned they don't care.
If someone fades to avoid DA/DF they are still seen as fair game if they ever get back on the radar, either as someone who needs to be DF'ed cos the elders can't stand someone playing the system, or as a lost sheep who could be reactivated. Anyone who remains in a locale and is well known by the congregation who does things that would normally require a JC to be formed stands a good chance of being hounded at some point.
If their argument is that they have a right to religious freedom and just want to leave then the JW line is clear - just disassociate yourself. No one is stopping you. Everyone knows that the only way of minimising the social consequences is to fade. Even then it's not certain how individuals will react.
The desire to judge is strong. The fear of those who have left is even greater.
I don't see anyone is going to buy some human rights argument since there is no one stopping anyone from just stopping coming or formally saying they are stopping. Even arguing about the social and family consequences has little traction from a human rights perspective it would appear.
