The question isn't "no advantage". I haven't seen anyone argue that here. The question is "how much of one" from the base line (which may start differently from a cis male), is there anything we can do about it to make sure the advantage isn't extreme, how much of an impact does that advantage really have on the particular sport (rastling lots, shooting little maybe even negative), what about the other way (what does treatment do from the other direction) and how much of an impact does that have on the particular sports. As before, it's a complicated question with no good answer.
Also the distinction with race is really simple. The science holds that this, like ADHD or autism or even being gay, is a natural condition which deviates from the mean. Race is not (at least not under the present science) since it is part melatonin and part cultural construct. If we want to get really messy there are some genetic conditions that may correlate to particular peoples within a race (such as the masai being really tall, but it doesn't follow that therefor all dark skinned people are tall). As far as I'm aware, identifying as another race isn't a condition which has been shown to be associated with differences in the brain.
Thats fair. I honestly could care less about who wants to identify as what and nor do I judge or dislike them for that.
I do care about M2F playing female sports. Obviously it’s a debate with strong arguments from each side. It will continue to be debated.
What I am absolutely against is any mutilation and hormone treatments of the body before age 18. Again, I don’t care what kids want to identify as but destroying your body before you are an adult is not something I will ever agree with.
