Welcome. I wish you the best of luck with your letter writing, but I suspect the best case result is that nothing happens. The WT corporation requires that you provide your name and congregation in any correspondence, otherwise that won't respond and, I suspect, won't bother reading it. This means that any sustained letter writing in which you are unrelentingly critical of any of their policies or doctrine is almost certainly going to result in your being disfellowshipped for apostasy.
I hope you win, and wish you the best of luck, but I fear this is too risky for you than it's worth.
