This was excellent.
I thought Harper was an excellent choice of interviewee (encapsulating both ends of the argument in one personage!), brave to do it and gave a very good interview. Emma was on excellent form and never an easy interviewer to face, when in investigative mode. Harper did a good job of staying calm and offering carefully considered words. Few people could do that so well.
The argument was given space to show itself so clearly for what it is.
Part 1, the science: There are significant biological differences between males and females, even after hormone reduction, especially in terms of strength. TW, post-hormone-reduction, are closer in terms of ability to women than to men, though distinct from them.
Part 2, the humanity(ies): TW athletes want to compete. They believe they should be allowed to compete in the closest available category to their socio-biological status, which is women's sport.
The idea that women athletes might have different wants, or that their wants might count for anything, is simply not considered.
I think sport needs its own 'super-straight' moment. For women athletes to show up the stupidity of the whole thing by declaring themselves 'super-femme', powered by female talent alone.
