I can see why it might be best to exclude transgender women from most disciplines, at least untill we have more science about whether they have any advantage in them, but as a whole this debacle just feels silly.
The rationale for the female category is to remove this male advantage from competition. Allowing a subset of males who have the advantage of their sex to compete against female athletes, just because these males call themselves women, undermines the whole point of women's sport.
This is why we need such testing as described in the article. It's no different in principle to, for example, weigh-ins in boxing that enable fair competition in each weight category.
Take that and then consider that this goes even harder for people whose bodies never masculinized due to androgen insensitivity or whatever. Maybe it still carries some advantage, but... so what? So does pretty much every single gene variant top athletes have and nobody is trying to single those out.
This is a line at which we ban accounts (https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...), so please stop doing this.
Also, please don't create accounts to do this with. It's not what the site is for, and destroys what it is for.
