Almost feel like I'm derailing the thread, but this is actually back on topic. 
Good piece by Colin Wright (known associate of Emma Hilton) about the protests at the swimming event.
Gender Ideology Is on Life Support. My Day Watching Lia Thomas Swim
I found the counter-protesters to be well-intentioned. Most were silent, some were polite, and a few were snarky and verbally aggressive. But what they all shared was passion as a substitute for knowledge. After very little questioning it became clear that they knew next to nothing about the topic they were so passionately out defending.
One of the counter-protesters seemed interested in data, confidently asserting that there wasn’t any good data demonstrating that transgender women who have lowered their testosterone levels have an unfair advantage over female athletes. Being close to the data on this issue, I responded that their claim simply wasn’t true, and that there were currently two literature reviews published in the most prestigious sports medicine journals in the world—Sports Medicine, and the British Journal of Sports Medicine. These studies corroborated each other’s results demonstrating that hormonal suppression does very little to close the large performance gap between male and female athletes. And, though it doesn’t really matter, the first author of the latter review is a trans woman.
The activists had somehow never heard of these review papers. “Were they peer reviewed?” they asked. Yes. “By who?” The journal editors and expert reviewers they selected. “How many people were in the studies?” These are review papers, so they include all individuals from every study on the topic. “Can you show me the studies?” Yes, here. That is how far I got with one of the activists before a security guard instructed me to go back to “my” side of the road to join the SWS protesters.
It was shocking to me that people with such a tenuous-to-nonexistent grasp of the relevant facts and data could not only be out protesting with such passion, but doing so while purporting to care about facts and data. When you haven’t spent even three minutes on Google Scholar doing a basic literature review on a subject, you shouldn’t hold such strong opinions.
