Here's why:
* Privacy: Information about someone's religious beliefs is generally considered private.
* Scientology's Secretive Nature: Scientology itself is known for its secrecy and control over information about its members.
* Family Dynamics: Family members often have different beliefs, and it's possible some of Tom Cruise's family may not be Scientologists.
It's best to avoid making assumptions about someone's religious affiliations based on the beliefs of a family member.
