right is of no sex

Without the vote women will be unable to change the laws that treat them unjustly.

All that distinguishes man as an intelligent and accountable being is equally true of woman. And if that government only is just which governs by the free consent of the governed there can be no reason in the world for denying to woman the exercise of the elective franchise. Our doctrine is that right is of no sex.
