What surprises me is that this hasn't happened in more countries. What surprises me is that civil suits in the U.S. haven't flooded the courts -- violation of civil and human rights because of the cruel act of shunning of disfellowshipped ones, even members of one's own family.
Because none of the laws you think apply actually exist.
You cannot compel people to associate, there will never be such a law in any democracy you'd want to live in and people should really drop this nonsense - it just isn't going to happen. We should stop trying to excuse our own or our own families dumb choices and attempts to make the WTS guilty for anything and everything rather than accepting some personal responsibility.
Were the WTS responsible for the lost contact with my parents / siblings? They had an influence, but only indirectly - the only ones directly responsible for lack of contact are whose who refuse such contact.
It's far harder for people to shun if you remove the excuse they fall back on - that the WTS makes them do it. Don't accept it, make it clear that it's THEIR choice that THEY chose to make and you hold THEM accountable for that choice.
For some reason it always reminds me of a quote in a book "Tell Them in Sparta" (annoyingly, out of print). The Spartans, talking about the Persian troops being whipped if they don't advance to fight, know that they just need to make them fear them more than the whips and they will turn and fight the other way.
Don't just "accept" that the shunning is inevitable and then let them hide behind it. Make it uncomfortable for them. Make it embarrassing. Make them have to say out loud "because I'm loveless turd of a person who choses to do what someone else wants me to rather than what is right". Make it more difficult to shun than it is to not shun and watch them turn and fight the people with the whips.
Just don't say "oh, you have to do what you're told and I accept that too". That's what the WTS wants. That's their rules and their system. Why live by it?
