I suspect this is what the Pro Transgender People will say, using myself as an example.
At no point in my life, no matter how much I trained, could I defeat Serena Williams in Tennis, out run the fastest female sprinter, or out swim Katie LeDecky. I was not good in any of those sports.
But your average male college athlete who transitioned in each sport could easily defeat all of them.
If you compare athletes at equal competition levels like High School, College, Professional and the male then transitioned to female, they will dominate the sport.
You could go so far as to say, males at one step lower in the competition ladder could dominate female sport is they transitioned.
For example, a top level male High School level basketball team could win the WNBA championship, etc
I remember there was a statement that said the 100th male ranked tennis player would wipe the floor with the number one female tennis player. And that with giving her the outside lines.
Serena was asked if she could compete on the men’s tour. She said nope.
