Either the women's category is a restricted class or it isn't.
If it is a restricted class, some people (in this case the 50% of the population that are male) are not eligible, and that will have to be enforced.
What practical suggestions are HRW making for enforcing the restriction? How would they do it differently?
How do HRW feel about qualification assessments for the Paralympics? Are they "policing of peoples' bodies based on arbitrary definitions of disability and racial stereotypes"?
("Racial stereotypes" makes as much sense as it does there applied to women's sport, so just left it...)
There is a sort of serious point here in that athletics dug a hole for itself by stopping routine testing. Previously every athlete competing at high level in female sports would have a chromosome test. It was routine, therefore not some sort of arbitrary "they look suspiciously male". So you couldn't have the "profiling" complaint.
If the new arbitrary non-universal checks are deemed objectionable, then they will have to return to the routine cheek swabs. It's not clear why the swabs were stopped - wasn't it just "it might be a bit of a shock to find out you've got a Y chromosome" if CAIS/PAIS?
As Sharron Davies has pointed out, this is a test that needs to be done EXACTLY ONCE IN A CAREER. Unlike the EXTREMELY intrusive urine testing for drugs and associated movement monitoring all high-level athletes are continuously subject to. To make a fuss about 1 cheek swab compared to that is laughable. She strongly advocates returning to that regime.
I'm also not sure the chromosome tests used covered all potential DSDs - do they catch the relocated SRY gene ones?
