We've always been gynocentric. Even the oldest religions have a basis in gynocentrism.

No. I disagree. This is of those "evolutionary psychology" myths which is simply a modern rationalisation of the behavior observed in current society, as is the rest of your comment (evolutionary psychology is bunk, but that is a topic for a different time).

Human society has always had a basis in differing roles for men and women, not gynocentrism per se. I'm not sure what you mean by "the oldest religions", but it's clear to me that Christianity, as an example, is patriarchal, not gynocentric. The difference is that under patriarchy, it is the male role to lead society and men have natural authority over women. Part of the role may be to provide for and care for women in their families and societies, but this is an example differing roles of men and women (equally, women were expected to care for their families and societies including their men, using their feminine abilities and talents).

That "gynocentrism" is natural is a myth usually justified by modern thinking that is inherently flawed. For example, a common "evolutionary psychology" argument is that women are more intrinsically valuable, usually justified based on something to do with how many babies a man vs a woman could have, which makes no sense since the limiting factor in human populations is the ability to successful provide for the population and raise children to adulthood, for which men play a more important role than women. This is the reason males (boys) have been historically valued more than females (girls). We can see that even today in countries such as China.

It is only feminist societies in which this is reversed. Yes, this is partly to do male roles in Western society becoming less important as there is less of a need to physical strength, but in is more to do with the prevailing attitudes in society rather than reality. Even in modern Western societies women do not survive independently of men, their survival is still supported by men except not men in their families, but the men who do all the useful jobs like maintaining the food and water supplies, electricity and transport, mining resources and building homes etc.

I also disagree that the "natural" sexual strategy of humans naturally follow is "a tournament species". This makes no sense. Humans have always lived in societies. While there may have been examples of successful "tournament" human societies when one man gets all the women, this is generally a poorly surviving society as it requires other means to coercing the majority of men (who have no wives or children) to defend and provide for that society. As opposed to a society made up of stable families, in which all members of the society have a strong stake of their own in maintaining the society. In the latter example, it does not mean there is no hierarchy in the society. The "best" men (who win "tournaments") still get the "best" women. But the men below that also get women, simply not the "best" ones.
