I was a bit puzzled to see some of the following quotes at http://www.fathersforlife.org/feminism/quotes1.htm#Femicommies, apparently intended to demonstrate that feminism is derived from Marxism:

Marxism and Feminism are one, and that one is Marxism — Heidi Hartmann and Amy Bridges, The unhappy marriage of Marxism and Feminism

Sexuality is to feminism what work is to Marxism…

— Toward a Feminist Theory of the State.
Catharine A. MacKinnon, 1989, First Harvard University Press. Page 3.

I wonder whether anyone involved with this page has actually read Toward a Feminist Theory of the State, or “The Unhappy Marriage of Marxism and Feminism.” In fact, one wonders if you have even read the title of “The Unhappy Marriage of Marxism and Feminism,” since that puts it in a nutshell before you have even made it to the essay. I ask these things because the two pieces are extended discussions of the problems inherent in trying to combine feminist and Marxist politics. The first 1/3 of MacKinnon’s book is devoted to a lengthy feminist critique of Marxism and of attempted Marxist-feminist syntheses.

There are plenty of places to find Marxist influences on feminism, or attempts to combine Marxist and feminist politics. But MacKinnon and Hartmann’s essays are not among them. Frankly it’s hard to regard the selective use of these quotations as anything other than (i) incredibly sloppy, or (ii) dishonest.
