Dianic Wicca is a branch of Wicca that focuses on feminist values and the worship of the Goddess Diana, often to the exclusion of any male God.
A few different traditions call themselves Dianic Wicca or Dianic Tradition.
Dianic Feminist Wicca Witchcraft Tradition
Dianic Feminist Wicca Witchcraft Tradition was established by Zsuzsanna Budapest in California in 1971 and continues to be influential today.
It is a woman-centered tradition that excludes men from its rituals and mysteries. This tradition has been criticized as separatist and focused on lesbian sexuality, but this is not the case.
Instead, it focuses on women’s mysteries and believes that men have other mysteries they should be focusing on.
Sexual orientation is of no consequence, though the tradition does seem to reject transgender women as their rituals at PantheaCon have been limited to “genetic women only”(( http://www.patheos.com/blogs/agora/2012/02/overview-of-the-pantheacon-gender-debate/ ))
Women who embrace Dianic Feminist Wicca Witchcraft Tradition may also engage in rituals with their male counterparts, husbands and sons who also serve The Goddess.
McFarland Dianic Tradition
