Italian Witchcraft....Do Italian's practice wicca?Witchcraft? Or Strega?

Strega simply means 'witch'. There are different types of Witchcraft.

Traditional Italian Witchcraft/folk magic is more often rooted in Catholicism and taught through the family line. It has little association with the Pagan revival.

Wicca is a specific religion-- a Pagan religion; while anyone (Italian or not) can be Wiccan, and I'm sure there are Wiccans in Italy, Wicca is a modern Pagan religion.

Stregheria, although it claims to be 'authentic', is also a fairly modern Pagan version of Witchcraft. It draws more from modern or reconstructionist Roman/Etruscan Paganism... but regardless of its influences, it actually started with the Pagan revival.

Every culture has their witches. It doesn`t mean they're all wiccan, though it varies for the most part, what things seem to signify as, in the regions.

Nobody does here.
