I've had conversations with many women on this topic. For the most part they feel somewhat threatened in restrooms and very threatened in locker rooms.
What do they feel threatened about, exactly?
Here's a poll from 2019:
"A majority of voters would support a law requiring public institutions to allow transgender people to use bathrooms that align with their gender identity or stated sex, according to the latest Harvard CAPS/Harris Poll.
The survey found 54 percent support for such a law, with a plurality, 44 percent, saying the Supreme Court should rule on the matter rather than leaving it up to the states, at 34 percent, or Congress, at 20 percent. Fifty-two percent of respondents said they would support a Supreme Court ruling finding that transgender people have a constitutional right to use a bathroom that aligns with their identity ...
... There is also a gender gap, with 54 percent of men saying transgender people should use the bathroom of their birth sex and 54 percent of women saying transgender people should be able to use the bathroom that best aligns with their identity."

And a study from 2016:
"We enumerate 1035 user comments from 190 online articles to gauge public opinion about safety and privacy when transgender women use female bathrooms. In these comments, we find that cisgender males are around 1.55× as likely to express concern about safety and privacy as cisgender females. Moreover, we find that when expressing concern (a) cisgender females are around 4× as likely as cisgender males to assert that transgender women do not directly cause their safety and privacy concerns, typically emphasizing their concerns are about ‘perverts’ posing as transgender females, and (b) cisgender males are around 1.5× as likely as cisgender females to assert that transgender females directly cause their safety and privacy concerns. We theorize that the heightened concern seen in males in these comments stems from them being more likely to view transgender females not as females, but as males who are lying or mistaken about their gender, and consequently they view themselves as protecting females from these males intruding into private, female-only spaces. This may be further exacerbated by a fear of deception and a belief that transgender people are mentally ill or ‘sick’."

In fact, it looks like the people who should feel most threatened by using their washroom of choice is .... transgender people!
"Transgender and gender-nonbinary teens face greater risk of sexual assault in schools that prevent them from using bathrooms or locker rooms consistent with their gender identity, according to a recent study.
Researchers looked at data from a survey of nearly 3,700 U.S. teens aged 13-17. The study found that 36% of transgender or gender-nonbinary students with restricted bathroom or locker room access reported being sexually assaulted in the last 12 months, according to a May 6, 2019 CNN article. Of all students surveyed, 1 out of every 4, or 25.9%, reported being a victim of sexual assault in the past year."

So, again, I'm not claiming that trans women are any more threatening than normal.
You kind of are though when you claim that women feel "somewhat" threatened by their presence in a rest room.
But the bigger concern is normalizing people who look like men going into women's safe spaces. Perhaps your personal experiences don't include that situation, I don't know?
How does allowing people to use the restroom of their choice amount to normalizing "people who look like men going into women's safe spaces?"
Where are all these people who look like men that are going into women's safe spaces?
And yes I know there are already imperfections with our current approach. But that does not give an excuse to make things worse. Do you agree that adding dread to people's lives is an issue? Like it or not, we live in a fairly utilitarian society. Typically we do not choose to worsen the lives of the many in order to slightly improve the lives of a scant few.
I don't see that as what we're doing, and polling and studies don't seem to back up what you're claiming.
No, I just have a decent understanding of the world and common sense. ER doctors must often make decisions based on statistics, correct? If a trans woman comes into an ER with abdominal pain, the doctors can rule out ovarian cysts BECAUSE biological sex matters, and in this case gender identification does not. Correct?
Then leave it up to the ER doctors when the patients come in.
Honestly with this, it sounds like you're just looking for problems.
