adamah, wow, I guess you have never encounted a non-jw who is anti-Halloween; won't send there kids to school to celebrate, preach about it at their church and condemn those that do celebrate; tell people that they are associating with Satan.....
Pentecostals
Baptists
Many conservative/born again religions
Orthodox Jews
Muslims
Hindus
I have people come to my door about politic issues, selling lawn services, selling school candy or pizzas, satellite tv, people from the local Lutheran and Baptist churches. I don't share their views or want their services. I just say no politely, and please don't come back. I know there are aggressive jws that require a call to the KH re do not call or posting your property No Trespassing.
As to huddling afraid in their house, the jws I know go out to eat, to a movie, shopping or to the meeting. The town I live in (and others) set a time frame for trick or treating, 4-8 at the latest.
We plan out handing out candy as we have for the past ten years. In 45 years as a jw, never saw anyone's home trashed because the light was off; they just went to the next house. Evidently I hit a nerve in my last post.
