Being a Witch (or Wicca) is a Religion just like being a Christian. On What the Housemates did next Mary said she would give being a Witch if it meant she would become a famous actress, This would mean giving up everything you believed in. Also during her party Mary says that the black pointy hats, cobwebs, spiders, caldrons etc. where the essence of her and what being a which is about being a real witch (Wicca) involves none of this stuff, it's just the old stereotype witch from old fairy tales.

I just have a feeling it was all an act.
