The feminist myth is that a long time ago, all societies where matriarchal and we all where happy. Then some evil man invented something called patriarchy. The myth is similar to the garden of Eden myth.

To paraphrase Jordon Peterson, there is no such thing as a patriarchy. There are systems where status is based on merit. Within reason, the more a system is based on merit the better it functions. A system based on merit doesn't have to be total capitalism or socialism, it is usually some where in the middle.

This is an interesting article entitled

The Myth of Matriarchal Prehistory Why an Invented Past Won't Give Women a Future

I was at least as impressed by the fact that anyone took it seriously as history. Poking holes in the "evidence" for this myth was, to rely on cliché, like shooting fish in a barrel. After a long day of research in the library, I could go out with friends and entertain them with the latest argument I'd read for matriarchal prehistory, made up entirely—I pointed out—of a highly ideological reading of a couple of prehistoric artifacts accompanied by some dubious anthropology, perhaps a little astrology, and a fatuous premise ... or two or three.

So here the author admits that it is a fiction.

However, a myth does not need to be true—or even necessarily be believed to be true—to be powerful, to make a difference in how people think and live, and in what people value.

Here the author admits the myth is useful. Now the author goes into hamster overdrive attempting to blame his myth on a man.

Since the myth was revived from classical Greek sources in 1861 by Johann Jakob Bachofen, it has had—at best—a very mixed record where feminism is concerned. The majority of men who championed the myth of matriarchal prehistory during its first century (and they have mostly been men)

So now it is the patriarchy that is at fault for this myth? All that is missing is some Jewish Cabal who has plans to take over the world. It was patriarchal Jews who created this myth?

Now she hamsters back to this.

Though there is nothing inherently feminist in matriarchal myth, this is no reason to disqualify it for feminist purposes.

So since the myth was created by men, it's ok for Feminists to use it? So what it the problem with this myth?

Relying on matriarchal myth in the face of the evidence that challenges its veracity leaves feminists open to charges of vacuousness and irrelevance that we cannot afford to court.

Oh, here is the problem. That it makes Feminists look bad when it is easy to prove they are lying. So in other words the feminist has no problems with lying providing it can not be proven she is lying.

Source is here. The author is bipolar as she oscilates between how it is a lie but then attempts to rationalize why lying is ok if it furthers a cause. But then she has the fear she will gets caught lying. But then attempts to blame this lie on the patriarchy. Must be difficult knowing your ideology is based on lies.
