If it was me, I'd sue the pants off Kim and Mikey.
Lawyers do not work for free. They are expensive. There must be something "at the end of the rainbow" to make it worth going through the litigation to sue for liable. If you've watched any of Mikey/Kim videos then you have no doubt seen their lavish studio office (NOT) and their expensive taste in stylish dressing/grooming (NOT), not to mention their obvious level of education. No sensible lawyer would walk across the street to sue these people.
It's obvious that they were JW's for most of their lives (gaving everything to the bOrg) and have paid a dear price for that. I think they are very sincere in their attempt to "expose the Watchtower" and while they (esp Mikey) often get carried away and boorishly long winded, I hope they are indeed helping/warning/enlightening others and finding a therapeutic value for themselves.
Let's review: It's a Cult!
