If you really believe there is no advantage then why does absolutely nobody care when ftm athletes try and play? It’s because they don’t compete anywhere near the top when they do that. When men transition to women they seem to have this uncanny habit of absolutely smashing records in women’s sports and taking the top spot in many competitions.

Sure not all mtf athletes just walk in and destroy the competition but it’s literally never happened a single time with a ftm athlete. Why do you think that might be? Could it just be a bunch of coincidences? Or could it be because there is an underlying issue with allowing someone who was once a man to participate in a women’s league?
