Protestants and Halloween

I've noticed that the families which dress their children as Saints for All Hallowed's Eve (and they do well) are exclusively Catholic families. No Protestants! How is it that you can justify celebrating witches and goblins and every type of fiction over the truth of Christ and His Holy Ones! Makes me wonder about the explicit and historical anti-Catholic nature of this secular celebration which has all of the marks of Free-Masonry, and, indeed, witchcraft. The name "Halloween" itself betrays it!
