Article I referred to before
Notable excerpts:
Vilain told me that the NCAA’s rules were also aimed at inclusivity and that the governing body aims to give everyone the chance to compete..... He said that the entire concept of anatomical equality for transgender athletes was simply not feasible, and thus, it was not a stated goal of the NCAA’s rules.
The purpose of the NCAA’s rules is to, in a sense, shift the transgender female athlete’s muscle mass and physiology away from that of the average male. The goal is to create a pathway to include the transgender athlete, not create total equality.
And from the cheat:
Here arguing against testosterone levels:
This study showed there is absolutely no relationship between testosterone in terms of performance in males. The relationship they found in women was weak and sporadic.
There is no evidence that having a higher produced value of endogenous testosterone has any performance advantages at all. The evidence does not bear that out. So that is the second myth: the more testosterone you have, naturally, the better you are. So trans women might be male early on, and that on average such bodies have more endogenous naturally testosterone, therefore they’re stronger because of that. We have evidence that is just not the case.
I don't know whether this is true regarding testosterone. I suspect McK is interpreting data in their own special way, but it does show that they are trying to argue against testosterone as being an advantage. The problem is that when an authority has introduced these limits they have implied that it is to make it 'fair' when in reality it is no such thing. But it then makes their position look weak when people start picking apart the basis for a certain level of testosterone for example.
Of course McK then goes full on batshit and argues that being trans is just a natural advantage like being tall is:
If you look at elite athletics, every single elite athlete has some kind of genetic mutation that makes them amazing at their sport....The question is not whether there is a competitive advantage, the question is whether there is an unfair advantage. .... Just because there is a competitive advantage doesn’t make it unfair.
Is being trans just another natural physical characteristic that, if — and this is a gigantic “if” — it provides an advantage, should we treat it like just being tall? ..... Is being trans just another way to be a natural person who maybe gets an avenge[sic] for it that we should treat like being tall?
