Obviously your insistence on communication through a lawyer is one of many things that irritate them about you and what you stand for. The WT hierarchy is not used to being told how to do things and is not about to change for anyone, least of all you.
They would rather be blatantly unjust than appear to respect your request, however reasonable.
I hope you do intimidate them. If so, you may have to go to several Thursday night meetings in a row.
Kind regards,
