I guess they have a hard time finding actual young women that would vote against their own interests.
The fact that the system gives them only two opposing, radical polarities, doesn't mean that there isn't nuance.
You and I may agree or not, but there are indeed young woman who, for example, are not pro-choice. They may have varied views on the trans issue, they have different class/economics policy goals.
You don't get to decree what young women interest are, neither me nor anyone else than themselves.
Is that not exactly what pro-choice means.
