Diogensister,
Agreed.
However, not having a central mandate for treating ex-members is a real danger. Because it gives liberty to individual units to impose their own rules.
The Catholic Church didn't have a clear rule on contributions, due to which the local pastor pestered the flock to tithe. In fact, apart from passing the contribution plate, he sent a weekly envelope to our home and even sent one of his assistants to gather the money from individual members.
It reached such an extent that four families in a year joined the JW's as they saw that no one forced them to contribute money to the kingdom hall.
In many developing and under-developing countries, people became JW's in throngs because of their notorious ex-religious communities, their unending money extortion, black-magic mired ceremonies, caste discrimination, etc. JW's were a welcome change for them and hence for them the "truth literally set them free". Shunning was the least of their woes.
In fact, of my cousins stated that he was happy that with the right bag of tricks, you can save yourself from getting disfellowshipped, and there are easy ways to escape the JW's without the threat of being hunted down.
I know because my family was one of them.
