The evidence does it support that theory, at least if you are using this particular girls soccer team as evidence of a sweeping change. The data is very transparent and is publicly available. One team of females in 9 divisions of mixed teams does not suggest anything more than an anomaly that we collectively would love to see grow and encourage more change. In Australia we have a well documented case of a women’s team wiping the floor with all opposition (female) and they have half the a team of trans m to f players. If the hope is that physiology is going to undergo a dramatic shift then there will be a long wait for evolution to run its course and whilst ever there i elite male sport that requires strength, stamina and testosterone, I would argue you will not see a broad change.
I find it far more comforting to look for changes in the brain structure and the way we think. If you accept that for the time being there will continue to be what we consider traditional males and females that continue in the mould of our ancestors, it is the balance of the population that provides the greatest potential for change. If boys in this part of the population are identified early, there is enormous potential for a third group which is the sissy (in whatever manifestation you prefer). Definitely not an alpha male and you don’t want the boy to transition to become female - that isn’t the goal. What is needed is a whole group or class that is easily identifiable as compliant, subservient, and happy with their role in life. The females in this part of the population need to be taught and encouraged to become the powerbrokers. You need strong assertive women that are able to take control and to be able to match the now dwindling alpha male group. The next step is how to reduce the alpha male group from being a dominant force on the planet to one where physical aspects are important but the brain is changed so that the heavy lifting and skilled jobs that require strength are completed but the participants are not interested in the power dynamics of a new order.
Another program that needs to work concurrently is the re-education of the traditional female. This could be achieved through placing the new sissy with a traditional female so that they get the experience of being in control and seeing just what they are missing out on by taking a more traditional or conservative stance. Having a sissy to cook and clean and carry out the menial tasks previously undertaken by the traditional female should be empowering and could be addictive and hopefully will change the mindset of this group of females so that the numbers quickly diminish.
apologies, this is a long way from the soccer field in a small corner of the UK, but it does attempt to show the extent of the challenge that is faced in making a step change in western civilisation😄.
