I too dislike these violent, creeepy all-American Halloween displays.
We have our own traditions in Europe and should promote them.
Until the Reformation All Hallows' Eve, All Saints' Day and all Souls' Day - 31.st.Oct. and 1. and 2. November were memorial days to the dead, as they still are in predominantly Catholic countries and in the Catholic church everywhere.
When exactly Americans added all these scary, and now frankly indecent elements, I do not know, but as a teacher I have been increasingly worried by the acceptance of violence in entertainment during the last four decades (at least.)
Children of all ages can accept a certain amount of violence in fairy tales, although many, as I myself did, are revolted by the more violent fairy tales, but even small children know that the world of fairy tales is not identical with ours.
What neither small children, nor teenagers realise readily, is that the violence shown in thrillers, horror movies, or even Jacky Chan films is dangerous. A film hero, be it Bond or Jacky Chan may survive being kicked in the head, blown up etc. but real men and women do not, or at least do not undamaged.
Human life is cheapened by violent acts being shown as entertainment, and this leads to youngsters copying their film heroes. Who would have dreamed when we were school-children that murders would be committed by 12 year olds, or young teens fight with knives ? Only those from the very roughest areas of the very toughest cities. Now these things are happening everywhere.
Is it not time to stop permitting violence as entertainment?
