WT doctrine can only GO OUT to the public from the governing body. There is no way to for the public to get information BACK TO the governing body - at least not in a public venue.
Their web site dispenses information only. They give talks at assemblies only. They write letters to congregations only. There can be no two-way conversation with the governing body - at least not in a way that the same audience can hear both parties speak.
Letters to Brooklyn are easily ignored and trashed. There is no way to respond at jw.org. They cannot be debated on stage at assemblies. There is no public forum in which they participate.
Why do you suppose that is?
