This isn't necessarily related to the feminism part of your question, but I've read some about modern day Daoist divination practices in China that are essentially like tarot cards. One book (The Souls of China by Ian Johnson) had an interesting perspective because some of the priests said there wasn't any magic involved and they weren't literally predicting the future. At least in that context, people have specific questions they want answered, and they have answers that they want. The divination only provides yes/no answers.

Someone asking if they're going to be successful some day isn't helped in any way by saying "nah sorry you'll be poor forever" nor are they helped by saying "yea you'll be a hollywood star" and having their ego inflated, but what they're looking for is some sort of comfort that their life won't always be miserable or meaningless.

So the priest guides them through their questions like a conversation and tries to give them the comfort they're looking for in the least harmful way possible. The yarrow root (or tarot cards, or whatever) are just the vehicle to have that conversation. You can say maybe that person should just go to a therapist, and maybe they should, but essentially the priest is trying to help people work through whatever issue it is they're having so they can come to some sort of resolution. And that's a role that existed before the contemporary therapist.

The idea is then that the 'prediction' part is just that person resolving to act in a way that would make it true. So if they ask if they'll be successful, the priest guides them to some sort of action they can do to work toward that goal.

I can see people wanting to use stuff like new age astrology and tarot and all that kind of stuff in a similar way, but the difference is that unfortunately, the person conducting those ceremonies may not have those good intentions in mind or any sort of philosophical, cultural, or ethical training to guide people to beneficial actions. They're not a community figure invested in the lives of the people talking to them, but a fortune teller with a building in the middle of town just advertising their services to random people for profit.

EDIT: As to how I feel about it, I obviously don't believe in it but I try not to bash it too much unless that person uses it as an excuse to be discriminatory or justify their bad decisions. Especially in more ingrained cultural contexts like the above, but even for the 'fairies and tarot' folks.
