A central point, which Talia’s argument stresses in bold colors, is the VERTICALITY of gender, of male supremacy. Something typically elided by imagining it merely as a binary (rather than a hierarchy)

And from the non-vertical conception you get the idea that it's like man---- trans*----woman when in reality it's man woman trans*

This generates the illusion that the problem of such a gender system is in its twoness rather than in its inherent character of violence, exploitation, and control
