Joe Rogan interviews one of the girls who left the westboro baptist church. Megan Phelps Roper, she was on the Louis Theroux documentary on this family.
If you do not know the family I am talking about, YOU GOT TO WATCH THIS. Louis Theroux's weird weekend > Americas most hated family.
Whether or not ya like Joe Rogan, this is a great podcast to listen to. This girl was brain washed, she talks about how she began to question the churches practices and how she eventually left the church. None of her family speak to her.
There's also another documentary on Netflix which follows two people who left the Orthodox Jewish church, these people are ostracised. This church controls their followers by banning them from speaking to non members of the church, they aren't allowed to use technology and read unapproved books among many other things.
All three people mentioned above were born into these churches and never knew anything else, incredibly brave people to question the practices and eventually leave knowing they will lose everything they have ever known.
