MeanMrMustard - "So what human right is violated by someone’s choice not to associate (shun)? The shunning comes from the members."
You're right, the shunning comes from the members.
But how many do you really think would do it if they weren't under threat of shunning (for noncompliance) themselves?
MeanMrMustard - "I know a bunch of Witnesses now that are in regular contact with DFed friends. They make that choice, and accept the consequences. Most of the time nothing comes of it."
Good for them.
If that kind of passive rebellion against the GB's fatwas were more common, things would get really interesting.
MeanMrMustard - "But I know a lot of former witnesses that would love to talk to their families - but their families don't want to talk to them. It sucks big time, but they believe it is right."
Don't make the mistake of confusing belief with compliance.
Besides, just how much of a "belief" can it really be, if (as a hypothetical scenario) the GB could abandon the WT's shunning policy with a word, and 7 million JWs worldwide suddenly felt free to associate with their DFed friends and relatives?
MeanMrMustard - "...the shunning doctrine isn’t really kept a secret."
Maybe not, but you can bet your sweet ass they don't focus on it much while they're recruiting somebody new.
All this is academic, really.
Even if the courts determined that shunning - as it is practiced by the WTS - isn't technically a "violation of human rights", requiring the rank & file to ostracize former members simply because of dissenting views is still unethical; and what's more, the WT publications have even stated this.
Demanding "unity at all costs" and enforcing it by authoritarian means whilst pretending that you're not is fundamentally dishonest and indefensible.
