Luce Irigaray, from "je, tu, nous: Toward a Culture of Difference," 12-13.

Women: Equal or Different?

To demand equality as women is, it seems to me, a mistaken expression of a 
real objective.  The demand to be equal presupposes a point of comparison.  
To whom or to what do women want to be equalized?  To men?  To a salary?  
To a public office?  To what standard?  Why not to themselves?

A rather more thorough analysis of the claims to equality shows that at
the level of a superficial cultural critique, they are well founded, but
that as a means of liberating women, they are utopian.  Women's
exploitation is based upon sexual difference; its solution will come only
through sexual difference.  Certain modern tendencies, certain feminists
of our time, make strident demands for sex to be neutralized.  This
neutralization, if it were possible, would mean the end of the human
species.  The human species is divided into TWO GENDERS which ensure its
production and reproduction.  To wish to get rid of sexual difference is
to call for a genocide more radical than any form of destruction there has
ever been in History.  What is important, on the other hand, is to define
the values of belonging to a gender, valid for each of the two genders.  
It is vital that a culture of the sexual, as yet nonexistent, be
elaborated, with each sex being respected.  ...  It is quite simply a
matter of social justice to balance out [patriarchal] power of the one sex
over the other by giving, or giving back, cultural values to female
sexuality.
