So ultimately she has to feel very secure, and if that means ruling out women’s colleges, that is fine.
But as another poster also suggested, my sense is these institutions (at least the sorts I named) are as deeply committed to welcoming kids like your daughter as any can be. And since they are not publics, and also not nearly as dependent on things like federal research funding, they are less subject to various forms of political pressure.
Again, though, if she wouldn’t feel secure, not a problem with me. But perhaps it would be worth doing something like talk to some current trans students, and see what they say about all this. Probably a good idea in general, really, not just for these schools.
I note there are various ways to make that happen, but one of the easiest is just to contact Admissions and see if they can put you into contact with a current student who can help. Among the pros of that approach is it is also a great way to demonstrate interest.
Just a thought!
