I think the reason a lot of women don't call themselves feminists is that the slander campaign against feminism has sadly been very successful. Feminists are seen as men-hating bra-burners who insist that all women should WOH and look as scruffy as possible. And that feminists want to put women above men, rather than on an equal footing. And since most women quite like men, as individuals, and are so culturally conditioned to need to look good, that embracing a movement which, in their incorrect view, means rejecting all they hold dear, of course they don't want to join in.
Perhaps we shouldn't ask women if they are feminists. It is just a label after all. Instead we should ask if they believe in causes like getting better education for girls in developing countries, stopping FGM and getting better and equal parental rights for everyone. You might find that they agree, and you have an ally, instead of getting all upset over a disagreement over labels.
I'm not keen on some of the more extreme views expressed on the feminism board, but I accept that different people have different views, and they are entitled to theirs. I don't think we have to agree on everything. There's no-one handing out Feminist Licences to women who only believe the 'right' feminist principles. Ignore anyone who tells you're less of a feminist because you don't happen to agree with them, they have no right to do so.
I can't help but feel that those of you rejecting feminism because you don't agree with the extremists are cutting off your nose to spite your face. I'm Jewish, I really don't agree with radical Jews who are occupying land in the West Bank. But I'm not going reject Judaism because of a few nutters. Instead, I'd rather show the world the normal and sensible face of Judaism, so that others can see that most of us are only trying to make like better and easier for everyone. I'd imagine the same goes for most Muslims. And the same should apply to feminism. The more of us there are getting out the message that it's OK to be a feminist and shave your legs, stay at home and bake cupcakes, the more other people will want to join in, IMO.
