Here's a posible idea:
Why doesn't twi add a full and accurate teaching about cults on their website. This would be required viewing followed by an honest discussion involving the twig leader and all twig members, especially for new people before they take the pfal class.
If the newer version of twi,
a) truly is new and has nothing to hide,
b) wants to show it has learned from the past so as not to repeat it,
c) and believes cults are dangerous
then, it would be a caring and helpful thing to do, in my opinion. The key here would be the words "full, accurate and honest." Having said that, maybe they should let a qualified non-member who specializes in cults do the teaching and facilitate the discussion. .
