A school in Mass. has cancelled Halloween festivities because the holiday "offends" the religious beliefs of some of its students' parents, according to this story.
Halloween is a good time for horror writers and horror fans. People like to be scared, and an annual holiday that revolves around ghosts and witches and monsters, where people are in the mood for fear, draws them to our work and to the things we enjoy is good for business. Also, there are lots of horror movies on TV for us to enjoy ourselves. In my family we like all the stuff that surrounds the Halloween season, too--monster displays in stores, the candy assortments, the jack-o-lanterns, etc. Doesn't mean we worship Satan.
Halloween is a traditional American holiday at this point. Not every holiday has, or should have, overtly religious overtones. Fourth of July? Thanksgiving? Arbor Day? Maybe Halloween does have roots in pagan rituals, but then, so does Christmas. Would the same families object to Christmas? Families who don't practice Christianity might--how would these anti-Halloweeners feel if that holiday was cancelled so as not to offend the Buddhists?
Sometimes people just need to lighten up.
