AJ,
Welcome to JWN!
I understand your dilemma juxtaposing the smear that they label "apostates" as "metally diseased," with the high numbers of people with true mental illness among their ranks. The religion appeals to people with mental disorders, and also makes members crazy with their teachings that make no sense. Many are suffering from "cognative dissonance" trying to reconcile conflicting statements from the organization.
You are in the right place, keep looking and sharing your story.
JK
