Two wrongs, do not make a right.  It is an old adage, but it still speaks the truth.
The circumstances she claims to defend (and I believe she does) do not exist on a scale of privileged grievance.  You cannot, with reasonable legitimacy, claim a desire for equality, while defending your right to behave in an manner which expressly inflicts inequality.
Her goal may be just, but her actions are antithetical to these very goals.  Her inability to see this, and alter her behaviour accordingly, belittles her cause, and discredits her moral authority.
