If transwomen were in male areas getting changed and going to the toilet, what do you think might happen?
I think there might be a few raised eyebrows. They might get laughed at.
peach If you haven't seen women being asked for evidence to support their concerns, you're obviously not much involved in this issue.
The Stonewall report doesn't support your claim that suicidal ideation or attempted suicide is caused by not being taken seriously when they try to exert their bodily autonomy. Body dysphoria is often co-morbid with other mental health issues.
The CNN report doesn't address either of the claims you've made.
The Williams Institute report is from the US. From that report, of the 93 people who answered the questionnaire, 4 reported being physically removed from the facility (this is not necessarily an assault) 2 were hit or kicked (assaulted), 6 were physically intimidated and/or cornered (not necessarily an assault), and 1 slapped (assaulted). One transgender male-to-female respondent reported having been sexually assaulted while using the men’s room.
There are far more instances of women being assaulted and harassed by men in women's bathrooms. That's a tiny number of trans identified men who were assaulted and all women's spaces will become less safe to prevent it. That tells you a lot about priorities.
