I am not into witchcraft at all either. I hate it too. But wizards are part of fantasy, just like Gandalf in Lord of the Rings (written by Tolkien who was a Christian). I totally respect your view though, just trying to explain the difference between real witchcraft, and magic coming from stories. Magic has been present in Fairy tales, games, stories, and is to me, pure entertainment and totally harmless.
Spells, arcane words, runes, magic, mana...all that come from the lore of Fantasy.
I believe there is danger in trying to use "magic" in today's world, very grave implications, a way to open doors to absolute evil.
This is a battle thread in DS, where it is all make-believe. I never use "spells" from witchcraft when I write my parts in the stories. It all comes from fantasy books I've read and PC games I played.
