LimeLeaf I don't know if you identify as a feminist at the moment but I'd hope firstly that any feminist of any flavour would wish to bring you over to the dark side into feminism in general before you decided (and you may not want to label yourself) what flavour of feminist you were. :)
I do not believe that radfems - certainly none on MN - would think that a reasonable plan for the future is to make women remove themselves from those they love. Separatism, as I understand it, is about choosing to remove yourself from the patriarchy as much as you are able to. It isn't about someone dragging you away from your home, shaving your head, giving you a mao suit and sending you off to a female colony where you may never contact men again.
IME when discussing men on FWR most feminists mean men as a class not the individual men you know. No, most men in the UK aren't removing all there partners wages and getting rich whilst forcing all the women to live in poverty.
However, if you look at the division of wealth it is vastly more men who are at the top earning lots than women and there are lots of women at the very bottom of society who are scraping by on nothing whilst doing jobs that aren't well regarded. Some feminists (myself included) think that it is the patriarchy that keeps men rich (and therefore powerful) and women poor (so powerless).
It's like the rape thing. Under UK law, only men can be rapists. Therefore men rape. This does not mean that every man rapes or that your husband is a rapist but men, generally, as a class, are rapists.
Hope that makes sense.
