The term y’all are looking for in reference to cis black women not having full access to womanhood is “ungendering” not transmisogynoir. Transphobia in combination with misogynoir is specific to black trans woman. It is their own unique experience

Example: in that thread, the person who wrote it made a list of black women who have been called transphobic slurs. Although those cis-Black women were called transphobic slurs or being likened to men, they were not experiencing transphobia. They were being ungendered.

we all remeber when Ciara was being called transphobic slurs, but she still has certain protections that come w/being cis that black trans women do not have.

We can recognize that ungendering for black cis women can manifest itself in the form of transphobic slurs and comments but that itself is not necessarily experiencing transphobia

All black people can experience ungendering. It manifests itself in different ways, but ultimately what is does is reduce us to flesh and leaves us open wanton violence
