Before I was banned from this group, I went to a meet up where in the general discussion a person mentioned a Women's Retreat. I don't recall which one she meant, but there are Pagan Women Retreats throughout the United States. This also is not a purely Pagan or New Age ideology. Christian Churches will have women's retreats, or even secular groups will engage in this dichotomy. To be clear, there are also male-only retreats or gatherings.
As the title suggests, I'm not a fan of this.
