I find it oddly paradoxical that radical feminist anti-trans threads always end up insisting on the weakness of women, and their inability to hold their own against men.
I was going to take issue with this as well. Someone even said upthread that women are "the second sex", the implication (if I rightly understood) being that we are lesser, rather than that we are unfairly regarded as lesser. Women are not weaker overall; we have different strengths. However, in terms of height and musculature, which is what is under discussion on this thread, yes, women don't have so much of either. We're talking about sportspeople, ie the fittest and ablest of, for the most part, young adults so the stereotype holds pretty firmly in this context. In sports that rely on skill rather than strength, equestrianism the only example that springs to my mind, women can indeed compete on an equal basis and on rare occasions are allowed to do so. The idea of segregating sports - and setting weight categories in martial arts - is to take pure size and muscle out of the equation and let skill shine through.
As for the subject of the article in the OP, there are two separate issues which I believe are wrongly conflated. That anyone is being called a freak, told they should be put down or die of cancer (why is it always cancer?!) etc, is unacceptable and downright disgusting. No-one should be subjected to that kind of abuse.
The refusal by the governing body to allow the athlete to compete in women's sports is being presented as another example of such intolerance, but IMO it is another matter entirely. You can't simply ignore the fact that this is a very large, muscular individual who competed on an equal basis with men and is now expecting to compete on an equal basis with women. Being less strong than before the transition does not = being weak (and if it did, do we currently let men compete against women as long as they're seen to be "weak enough"? No, we don't). You can't in all fairness compensate someone for being (verbally) abused by allowing them to (physically, in this case) abuse someone else, and let's make no mistake, if this individual gets into a real rough-and-tumble match with your average woman player, someone IS going to get hurt. And it's not going to be Hannah.
IMO this is the whole problem with the trans debate (or should I say #nodebate?). On the one hand there's unthinking bigotry with which no-one decent wants to be associated. On the other there are real issues which need to be thrashed out so that no-one suffers more than necessary. (Would that all human conflict could be straightened out with love and understanding...) Don't let us allow the former to blind us to the latter.
