You already have great "No, thank you" advice here. Follow it.
I was offered a "study" with two elders focusing on the organization because
I resigned as an elder stating that I don't fully "know" the Faithful Slave and
cannot promote their doctrines, so the only counsel I got was to study with
them.
"Study" is a way to enforce upon you to "agree with the doctrine" or else
gather evidence that you are rebelling. They don't always intend to do the
latter, but they expect to just re-indoctrinate you if they point out the reasoning
of the WTS for anything you question, then you would go along. I wasn't going
to give them a chance to gather evidence that I would not "go along."
NO, THANK YOU.
In your situation, it was not wrong to go to the Memorial. You went to all the
trouble of reinstatement. Your fade since then would have to include some of the
big events. Next year, perhaps you can go to a different hall just to say you went.
