Had this actually happened somewhere, or is it just a hypothetical? Like trans women assaulting cis women en masse in women's restrooms.

Also note that Fox has not won all of her fights, which indicates that trans women are not as dominant as the one fight you mentioned would suggest.
1. Do male athletes dominate female athletes in competition? We know the answer to that is yes, in almost all sports. It's why we have a separate female category, and there is a wealth of evidence to support this - from biological studies by sports scientists to comparisons of world records.
2. Are there any interventions that male athletes can take upon their bodies to entirely eliminate the male physical advantage in sports? From the evidence we have so far, the answer is no. They can be weakened through testosterone suppression, but in general they still retain a significant advantage over female athletes.
There is also the question of whether an impaired male athlete should be considered equivalent to a female athlete for the purposes of eligibility in the female category. This is more of a philosophical question and leans heavily on whether one believes that "trans women" are women or not. Is it fair to impose this belief on others who do not share this belief - particularly female athletes who may fundamentally object to being compelled to compete against men?
It's almost like what they say they are concerned about isn't what they are really concerned about.
At this point it's hundreds of male athletes competing in women's and girls' sport: https://shewon.org/males
The thing is, the best athletes frequently have genetic privilege that others don't have, whether it be extra long or extra short limbs, being extra tall, having higher than average testosterone levels, etc. There is no level playing field.
I don't know what the best answer is, but what we are seeing now is pretty ugly.
In most cases though it's very obvious when a male is in a women's event. For example, no-one is going to mistake this male, who competes in women's cycling, for female: https://i.ibb.co/N6ZBzh4K/F4-Svyxt-XYAAMpc-M.jpg
The best athletes often do have some sort of genetic privilege, that is true. But look at the world records of pretty much any sport and compare the most elite male athletes with the most elite female athletes: the difference is massive. Even having advantages in limb length, lung capacity, and so on doesn't overcome the physical advantage of male development.
Support candidates that appeal to the electorate. Find common ground. Resist demonizing the opposition. Moderates shouldn’t have to choose between polarized extremes. If you are intellectually honest you may see the ripple effect created by unfairly shutting Bernie Sanders out of the democratic nomination in 2016 set the stage for this outcome .
