Background
Jehovah's Witnesses have faced criticism and internal dissent for various reasons:
Doctrinal contradictions / failed prophecies: The organization has made predictions about world events that did not materialize, leading to doctrinal changes and disillusionment among members. (en.wikipedia.org)
Science and logic contradicted Bible teachings: Some members find conflicts between scientific understanding and the organization's teachings, leading to doubts about the faith's validity.
Moral issues with Watchtower leadership: Allegations of mishandling child sexual abuse cases and associations with organizations like the United Nations have raised ethical concerns. (avoidjw.org)
Personal mistreatment or emotional trauma in the congregation: Experiences of abuse, neglect, or emotional harm within congregations have led individuals to question their involvement.
Shunning / family pressure / fear-based control: The practice of shunning disfellowshipped members can result in severe emotional distress and social isolation. (pubmed.ncbi.nlm.nih.gov)
Realization it’s a high-control group (cult-like tactics): Some former members describe the organization as employing high-control tactics, limiting personal freedoms and critical thinking. (en.wikipedia.org)
I was never really convinced: Individuals born into the faith may never fully embrace its teachings, leading to eventual departure.
