EB's mum on Twitter seems quite upset by the decision, generous (to EB's ilk) though it seems to me.
I'm not sure what I think of the mother's response to this, it can be fine balancing act as a mother, your support for your children needs to be staunch but not unconditional.
Anyway, she retweeted some posts by a trans sports person (I'll leave you to guess their sex/gender combo) arguing that trans women can't possibly get their T levels down as low as the newly required levels (i.e. very deep into the 99th percentile for females), all of which struck me as a load of old rot, including this doozy:

...individuals with XY chromosomes need a higher level of testosterone those with XX chromosomes to maintain basic health, due to their androgen receptor response. t.co/1kBQFn4mmx
it's almost as if the poster is arguing that, gosh, men and women are very different, with vastly higher T levels being the norm for men.
