• first of all, this disagreements just focuses on the ‘birth’ part, which is not the main part of my original statement. Replace ‘place of birth’ with ‘place of education’ or ‘origins’ and you got the same result.
• second, you can always find advantages to being born in France, even without growing there : better chances to have parents who excel at pétanque, better chances of going back to learn, or even better birth hospitals or whatever. I’m not trying to make a good point here, just finding a bs justification, because that’s what ‘being born male gives advantages’ is.
• last, being born male can also comes with innate disadvantages (less tolerance to pain, less flexibility) and acquired disadvantages (less elegance, more competition), not even including the hardship of being trans in our societies and the impacts of transition treatments. ‘Male chromosomes advantages’ mostly are strength and endurance, which are not the only factor in sports. Plus most of the factors that disadvantage women in sports come from social background rather than biological ones. And in the end, we cannot observe an overwhelming winrate in favor of trans athletes. ‘XY advantage’ is just a dumb argument that only makes sense when you don’t look further, just as the dumb argument i give for the impact of origins/birthplace/nationality.
