Raven -
please Google 'Shepherding the flock of god book" the JW's 'Elders Only' super secret, confidential, clandestine cult manual is all over the internet (and many thanks to those who put it there!)
On page 73 is where your situation is discussed - item 40, last bullet point reads
" is the person willing to meet with a committee, thus admitting accountability to the christian congregation?"
You have already left - do not ever again meet with these assholes as they will interpret your attendance
as your legal admission of their "ecclesiastic authority" over you, and you nor your lawyer will have grounds for your claim of freedom of religion - (which is the real legal issue they violate by harassing you)
You have a guaranteed right to be free of any religion you wish - the right is granted to the individual citizen, not the religious corporation.
Norman Hancock won a case against the Mormons on grounds similar to yours.
