It is also what bemuses me - the IOC has access to the smartest sports scientists in the world. So, how can they come up with such a shambles?
Because science is the business of understanding and explaining reality, and reality (according the currently dominant construction of gender ideology) is transphobic.
I’ve mentioned this before, but the problem with an ideology that is in conflict with reality is that reality keeps poking through. So the ideological becomes more and more complex with more and more workarounds and special cases to deal with all the gaps between how it asserts the world is and how the world really is.
