Very cut and dry IMO.
If you were born a male, then you produce more testosterone than somebody born a female, which contributes to muscle mass and performance improvement. An average man has a bigger structure, more muscle mass and basically far more physical strength than an average woman, any given day.
If you were born a man then you should not be able to participate in a women's sporting event, especially at higher levels.
Example: Gavin, I mean Laurel Hubbard, is 6-foot-1, 287 pounds female that transitioned from being a man. He set national records in junior competition (under 20). She ignited protests of unfairness after winning two gold medals and a silver medal in the 2019 Pacific Games while being the oldest woman in the Olympic competition, at 43.
