“This research doesn’t align with what I believe to be true. Ergo, it must be wrong”
It's the wording, "no scientific evidence." It doesn't mean you can't credibly infer that there must be advantages having been born a male. What research and scientific evidence and statistics can there be considering all the factors? You know how for the longest time US PDRs used to say there's no scientific evidence anabolic steroids improve athletic performance. And as I've said there's no scientific evidence the vast majority of drugs on banned lists improve performance. You'd need a ton of research to gather data, ain't got time or interest in all that.
Having been born a male: bigger bone structure, bigger lungs, more muscle fibers and satellite cells, even the brain is different, just to name a few.
A lot of times the trannies have been really bad male athletes before suddenly winning as females. Imagine gifted male athletes crossing over.
