I’ve done a great deal of work to help myself and others heal and rebuild their lives after leaving the cult. This has been through personal relationships as well as by participating in workshops for ex-cult members, which I have done as both a participant and a presenter. All of this has been immensely rewarding and productive.
But if by “activism” you mean trying to change or reform the religion, forget that. It’s a complete waste of time and effort.
Martin Luther nailed his 95 Theses on the door of Wittenberg Castle 502 years ago on 31 October 1517. Sure, it started the Protestant Reformation, but it didn’t end the Catholic Church. To my way of thinking that just made things worse.
Trying to reform the WTBTS is a complete waste of effort.
