"Have I got this straight?"
That's about it, according to the anti-Halloween folks.
It's interesting to go to one of the old cathedrals in Europe. They're practically covered with images of demons and the like. I suppose the idea was to put the fear of God into the church-goers, but it's a very odd thing to experience.
Halloween is a silly Autumn holiday. Get that last outdoor activity done before the snow falls. Go meet your neighbors and let your children see that they're kindly folks. Give out goodies to the neighborhood kids. Tons of fun.
Sometimes Halloween is a couple of days too late!
