Phew. Too many things to respond to, but I read all of it, and I definitely see your perspective on many things and understand the unique challenges trans people face.
Specifically in the conversation of sports, I see the other side of it. The male/female distinction in sports doesn't exist so you can play with your peers. It's due biological differences between people born male and female. I understand that you will add massive amount of context that is very specific to trans people, but to most people, it is a very simple thing that does not need to be complicated by medication or body composition, or anything else.
Your comment about not distinguishing between competitive and non competitive sports is literally my point. It should be distinguished. Trans community should be saying "we just want to play with our peers, we don't care at what level". This would make the conversation much different nationally.
No, I make it sound like forcing trans girls into locker rooms with male athletes puts them at higher risk of being sexually or otherwise assaulted than they otherwise would be.
Is this actually based on anything, or is it just an idea that you think makes sense that isnt actually representative of where sexual assaults come from? I genuinely wonder as it just doesn't make sense that sexual assaults would come as a result of sharing a locker room. I would guess that allowing trans women to play women sports would have a 0% impact on the stat.
There are many sports where females are on male teams already, and each one of those needs to take into account the locker room situation. For trans women, this should be considered as well. And if it's not, that is a problem with the administration, not with the sport structure.
