There is no doubt that if you are completely sure that transwomen are women in every possible way, then of course they should be able to compete in women's sport. I don't agree and I can't imagine a situation in which I would, so of course the Fair Play poll makes sense to me. I don't regard the International Olympic Committee as an objective organisation with integrity or real concern for women; I think they are quite malign and I have lost any remnants of romantic feeling about the Olympics, which is probably a good thing. Therefore I feel the influence of their rule changes in 2004 and 2015 are not positive for women's sport. Having competed in women's sport in the past I know how little any man cares about it, and a lot of women don't care either. But I do.
I am not an uncritical support of the IOC in any way. Their treatment of sports which stand up to them on and demand genuinely effective doping control, for example, has been just as appalling as some of their treatment of women's sports in general an many women in particular.
Where I disagree is that the rules in place for the potential inclusion of trans people in the Olympics from 2004 onwards have not created the doomsday scenario that many claim.
Further, the key group which has benefitted has been trans men who for whatever reason, compete in men's sports in considerably higher numbers.
It's also not the only successful trans inclusive policy in sport.
On the other hand, the American bills forcing people to go through genital examination and the scandalously poor treatment of cis women like Caster Semenya do precisely nothing to 'protect' or 'enhance' women's sport and everything to increase barriers to access, especially for black athletes who are disproportionally targeted.
