It will be interesting, I think, dittany, to see how my students respond to the juxtaposition of theorists and writers such as SdB, MacKinnon, and Dworkin, who address real women's issues directly, such as marriage, rape and violence; and those theorists and writers who philosophise "woman" or "women's ontological experience", and frequently address the aforementioned issues indirectly, such as Cixous or Irigaray. I disagree with you that the latter are not feminists, or worse, anti-feminists, but acknowledge that the effect of their writing is radically different, and that is worth thinking and talking about.
Indeed, it is precisely the fact that - as you point out - Dworkin and others provoke howls of outrage, while others - such as Cixous - who arguably (I know you do not agree, but please accept that I do!) make any number of accusations against men, yet couched in a particular style/language - are more "acceptable" (I think this is largely an impression of their more "academic/intellectual" [however specious those terms are] qualities, if you see what I mean), that needs examination. (Ugh - ungainly sentence... Hope you follow me).
And it should be pointed out that your picture of the academy is not quite as accurate as it may seem. Plenty of (predominantly male) academics utterly reject Cixous' and Irigaray's thought. They haven't "won" any particular war; a few battles, maybe. However, I do agree that in comparison to the fate of radical feminism in the academy, these thinkers are virtually canonised.
I wish that it was not such a zero-sum game; there should be room at the table for all kinds of feminist thinkers. Not in the spirit of forced (feminine) tolerance, but in that of a kind of open-minded arena which admits different species of debate, while not losing sight of the real world, real time, real life goals of political feminism. And it should not be the case that thinkers muscle others out. That is, surely, a patriarchal gesture. But the remedy to that is not then to replace one orthodoxy with another, if you see what I mean, which would arguably simply replicate that previous patriarchal gesture.
Incidentally, in Cixous' case at least, it is not quite fair to claim she has done nothing for women directly, since she founded the centre for Women's Studies at Vincennes, which was (hazy memory, I think) the first of its kind in Europe. That is surely, if only an academic action, a positive one for women.
And Irigaray initially suffered for her opinions, when she was ejected by Lacan from the Ecole Freudienne.
