They are not demons. Sorry, I won't prove this one to you. You will just have to trust me on this one. A witch cannot shed tears. A witch cannot look a man in the eye.
Witches sink in water.
Witches sacrifice animals. Witches say the Lords Prayer backward during rituals. Witches have group and same sex, sex during rituals. Witches are ugly, have warts and wear pointed hats. But all this doesnt mean I can't cast spells, both good and bad.
