Sirona:
Being a professed witch, I can't understand your sensitivity about the "occult" celebration of Halloween. Samhein was a celebration of the Celts who thought the spirits of the dead returned to earth to visit relatives and friends on October 31st. ("Occult: l. pertaining to, or dealing with or knowledgeable in supernatural influences, agencies or phenomona." American Heritage Dictionary) Some historians note that Celts often dressed in grotesque costumes to ward off the evil spirits of witches, faeries and demons on that particular night. (So evidently even some pagans had a dim view of witches.) If true, it seems strange that witches would even choose this night to celebrate.
Regardless of how hard followers of Wicca try to project a different image today, the origins are based in the occult.
