But - if in other sports it's as easy as "having an F on your passport" then do we not think that other countries will see this and take advantage for 2028?
In most cases it isn't - "having an F on your passport" is the IOC's preferred policy - as of about 3 years ago, having given up on testosterone levels, or even the belief that there is an inherent male advantage that justifies separate events.
But most sports events at the Olympics have their rules set by their own international bodies, and those bodies have been moving pretty much universally in a direction of removing trans and DSD loopholes permitting males into female sports.
This is an exceptional instance of the IOC getting to actually run a particular sporting event their way. And an example of why they should never be permitted to.
The IOC doesn't really seem to be a sports organisation - they just identify as one.
