I'm pretty sure people with CAIS can still compete in the female class at all distances as they derive no benefit from the testosterone at all and I'm onboard with that. Any DSD athlete that has the benefit of utilised testosterone above what is considered normal for a woman should not be in the Female category.
No, CAIS are still male and may still have male features that benefit them athletically. It's not just about hormones, there is also skeletal structure, blood cells, heart and lung size. There is no guarantee that every single physical feature of sufferers of CAIS (besides the reproductive system) appears female. We have to draw a strict line because genetic males with DSDs have done nothing but take advantage for decades.
There are cases of males with CAIS completing at a high level in women's sport, which says it all in itself. Elite athletes are rare and exceptional, and CAIS is extremely rare (between 1/20,400 to 1/99,000 male births). The chances of someone just happening to be both immensely athletically talented and incidentally having CAIS ought to be astronomically rare to the point it's non-existent, unless their CAIS is benefitting them in some way.
I wonder if many Muslim families are aware of this yet, I would have thought Muslim parents' views are taken seriously at the moment, remember the teacher that got hounded out for showing an image of a religious icon? They were vocal outside the schoolgates then ... Why aren't they vocal on this issue?
I think they just see it as white liberal infighting and don't really know much about it. They probably just think TIMs are all super-gays and not of concern to their daughters.
