She can write that trans women pose no threat for so-called cis (sic) women because she clearly hasn't done any research on it. Her forte is the optimistic and breezy style and instant intuitive observations. It's not the kind of jaw-breakingly boring work that one must do to understand that 'cis' does NOT mean just a woman who is not trans, but a woman who has a special woman essence in her mind which just happens to match her body. So all 'cis' women are expected to be completely happy to see the female body turned gender-neutral because their identity is that essence in their heads, nothing more.

She clearly has not thought through what will happen when we have no acceptable way of talking about female people. Because if we can't name the people who are of female sex, then we can't define the targets of sexism etc.

But yes, she certainly has not even Googled the topic of incidents in toilets/bathrooms. I have quite a few in my files.

I think she bases her arguments on some very nice trans folks she has known in her life and not on what today's trans activists are demanding. But what matters for women's rights is the latter, sadly, and not the fact that many trans people are good people.
