Hey whatif, I think my parents were a bit more strict then others. My dad was PO and my mom was a pioneer during my younger years. I remember my mom telling me, her parents disowned her when she became a witness. This would have been back in the early 70s. My dad was from a large family in Delaware, non of his family were jws either. My parents moved to where the need was great, far from their families.
Based off what I remember my parents in no way shape or form wanted to appear to celebrate any holidays because they may stumble someone else.
