The unjust thing about such a disfellowshipping, if what you said was later taken up by the G.B as "Noo Lite!" you would not automatically be re-instated, if you wanted to be. Maybe not re-instated if you requested it, in that you should not have disagreed with the G.B at the time, you were being "Disloyal", why should one be loyal to an opinion by the G.B if it is not Truth ??
If I had loudly voiced my many disagreements with the G.B's opinions ( and that is all they are) over the years, I would have been DF'd multiple times !
