It’s weird how we let children do all sorts of medically warranted things with parental consent under the consultation of a medical professional. It’s almost like if consent is the issue, then the entire topic is a non-issue because we’ve already got a system in place.
You don’t need to consent to other people’s children’s medical care. It’s none of your business. Fuck off you nosy bastard.

None of that, or your oft mentioned papers, have anything to do with the fact that it’s a vanishingly rare occurrence and not worth caring about. I honestly do not care if a trans woman is better at basketball or not. It’s sports, it doesn’t really matter unlike “respecting people”, which does matter.

As for 3… Has it ever happened? And what does it have to do with transgender people? Do they check your ID for gender on the way into the bathroom? What’s to stop a cis man from walking into a woman’s bathroom and doing whatever you’re afraid of without a disguise? Do you think cross dressing and a wig will make people just let the assault happen?
Do you think women will be more comfortable with a bearded man in the bathroom? Because that’s what you’re advocating for. If trans women can’t use the women’s room because a cis man might sneak it, then trans men must use the women’s room, which makes it easier for said cis man to sneak in. A cis man looks a lot more like a trans man than a cis man looks like a trans woman.

How concerned are you about making sure that police don’t get into women’s spaces and commit evil acts? The barrier to becoming a cop is lower than changing your gender, so the path of least resistance is to become a cop. You’ll probably get a paid vacation while they investigate your evil too.
And that’s not a hypothetical by the way. There are more sexual assaults by on-duty police officers than by trans persons in total, or by trans impersonators. Far more. So if you’re concerned for women’s safety, start there. Or almost anywhere else, statistically.
