She does seem to prove that some exjws give the exjw community a bad name. Of course, if the GB had any imagination, they could create false flag situations where loyal Bethelites pretend to be exjws spouting crazy nonsensical crap. "The GB are a secret society that sacrifices babies" is the sort of thing only going to make current JWs roll their eyes, at best!
I'm not saying that the GB create false flag situations. As I suggested above, I doubt that they have the imagination. Some exes damage the cause completely free of help from mysterious secret organisations. 🙄
