this a statement or a question?
while people study and practice both, witchcraft is a practice, while Wicca is a religion. if you cast spells, you do witchcraft, if you pray to the God and Goddess, follow the Wiccan Rede, the Threefold Law, and the eight Sabbats, you practice Wicca. just because you cast spells doesn't mean you're Wiccan. basically, that's the different. it's the same as saying all Wiccans are witches, but not all witches are Wiccan. it's a title, the two are similar, but Wicca is a religion, witchcraft is a study. [some do celebrate certain holidays, and do pray to deities, but it does not follow the same rules as the Wiccan religion.]
