"Chaserious - Why do you think we who are DFd are powerless? We, ALL of the DFd, and all those who have EVER been DAd - are the very people, the living witnesses who can prove that, the WTS does indeed incite ALL their members, including our own close family members to discriminate, without known cause, against us. WE the DF'd and DA'd are also the living witnesses and proof of the mental and psycological damage that is unavoidable under the WTs extreme, coercive, systematic, alienation . I would imagine thousands, would happily volunteer to testify to these as legal claims if given a chance. Hopefully, Band On The Run, or some other legal eagles will join in here."
I don't think we are powerless. Numerous websites have been started with large followings that expose the WTS for what they really are. But from a legal standpoint there is absolutely no grounds for suing the Watchtower because of DF/DA. Every week someone posts a thread saying there should be a class action lawsuit for all of the evil the WTS has done. Do you know why it hasn't happened? Because it would be an enormous failure. If anyone has individually been harmed by the WTS to the extent that the law recognizes a remedy, or a plausible argument can be made that the law should recognize a remedy, then by all means they should bring a lawsuit. I hope every pedophilia victim does bring a lawsuit against the WTS. But there is no such thing as a giant class action against a Church for all different kinds of emotional harm. You cannot sue churches for matters relating to core religous doctrines that you don't like.
You keep bringing up Rosa Parks. Rosa Parks took action against a government policy. The WTBTS is not the government. If the WTBTS, or the Podunkville First Church of Christ or any other church wanted to discriminate on the basis of race due to their religious beliefs, like say refusing to allow black couples to have a wedding ceremony in the church, guess what? They could do it right now, in 2013, and they could not be sued.
ETA: Think of it this way. We know that gender is a protected status in the Western world. The government could not force women to sit in the back of the bus any more than they could force minorities to do so. But it's not protected within churches. Imagine if all of the women who felt it was their life's purpose to be Catholic Priests decided to bring a class action against the Catholic Church for denying them their life's calling by not allowing women priests. Everyone knows the courts are not going to recognize such a claim. You are suggesting basically the same thing, except an even weaker claim, because at least women are part of a protected class under the law. People who leave or are kicked out of various religions are not a protected class at all; or what in the U.S. the courts call "discrete and insular" groups that need protection.
