With that said, however, he is exactly right when he attacks them for conflating "Feminism" and Marxist social thought. Feminists should not necessarily defend minority groups, now should they be concerned with racism or post-Colonialism due to their being Feminists.
One of the cruxes of contemporary feminism is "intersectionalism", meaning they view all the familiar 'isms' as being interlinked, or even fundamentally the same phenomenon. Moreover, contemporary feminism in the world - including in the United States - draws mostly from post-war Continental philosophy, which on its own developed various elements of old-school Marxist thought in ways that the old-school Marxists themselves disliked (and still disagree with, wheresoever they remain).

In other words, you are out of touch. The classical (now "conservative") feminism you have in mind is overshadowed by the dominance of post-modernists.
