Few if any religions are as hated by ex-members as the Borg. Few, if any, X-tian religions are based on control of the sheeple as the Borg. DFing is the primary means of control. Do the math. I'm with Hoser and EyeUsetoBeaDub - unless governments threaten actions against such behaviors the Dark Lords will never change DFing. They might reduce the numbers of new DF cases (adopting a 'keep your friends close but your enemies closer' strategy) but do any of us really think they will break down the walls that separate US from our families and friends still trapped inside the cult?
I have stated before that I believe the ex-JW activists would be more effective if they developed a political action committee or established a lobbying organization in major world capitols to try to get legislation passed to curb or end DFing based on it being a hate crime that destroys families, thereby causing real problems for governments. It would likely only take one major W country to ban religions from DFing to make the Dark Lords change the policy.
