It's happening alot. Many schools are barring Halloween activities, instead holding "Fall Festivals"; Renaissance Fests; Storybook character parades, etc....
It seems like every year, there are more and more who vocally object to Halloween, and instead of just keeping their kids home the day of the costume parade and Halloween party, they are seeking to impose their minority opinion on the majority, and in many instances, succeeding.
I resent these alternatively themed events, because it means I have to provide two costumes--one for school and one for Trick or Treating.
My son doesn't participate in Halloween activities. Our personal convictions--this is America and we're allowed. No, we're not Wiccans! Every year I contact his teacher and tell her we don't celebrate, and he is provided with an alternate activity during the big Halloween dress-up party at school. I would NEVER think of trying to ban Halloween for the school. We are in the minority in our community. As long as we have the choice to opt out, what business is it of ours?
