Hello Radar,
We must remember Radar that the WTS does have a right to disfellowship its members. Infringe upon the rules, clearly stated in WTS literature and you run the risk of being DF'd. The WTS defence of 'you knew the rules when you joined' has been repeatedly upheld in the courts over 30 years as a legal right.
The issue is whether it is morally right for the WTS to do this, whether 'shunning' which is entirely different to DF is scriptually based and sustainable ethically, and if the DF process is used as selective weaponry upon it's hapless adherents.
