After being seared by their vindictive policies (albeit second hand) I have slowly healed and come to the conclusion that I am glad they have the policy they do.
People are getting DFd and after an attempt to come back (usually met with a "not yet") they give up altogether. Most of these are young people who will go on to marry and raise a family not tainted by the Org and its policies.
Others still in will see how well their lives work out in a compare/contrast and be emboldened to leave also.
This is one way the Org is participating in its own well deserved self destruction.
