Follow up on "wife"
where he raises the issues of segulah-centered rituals in which women participate today, excerpt here:
But since this has developed into woman's work, and she is the one who does hafrashat challah, this has been changed into a ritual for a coven of women. They get together in groups made up of specific (in-)signicant numbers of people, have names of people who need a shidduch or a refuah sheleima, and have them in mind when they perform their ritual. And they come up with silly "fluff" about the mystical significance of the ingredients of challah, and so on.
Women's prayer groups are the efforts of feminists to practice rituals usually reserved just for men. But the "frum" variant is more problematic, in my opinion. They consider Amen to be a word of power, and they meet at the new moon.
