I actually don’t think it is the best, but I wouldn’t be so egotistical to tell someone else how to live their life. I’ve been there, done that, as a JW.
i do think ex-JWs should put their own healing first, and then see if they are still interested in being an activist. It is too easy to get stuck in a place of being angry and hurt, and not get past it. If this is their way of making sense of the cult experience they had, and it helps them heal - I am all for it.
