enough critical thinking to know male violence when they see it.
I agree Vestal, and I would say that women's shelters would never have been established had feminists not come up with an analysis that placed male violence against women and children in a broader political context, instead of accepting the 'wisdom' that had held true for centuries, that some men beat their wives and kids and that was just the way it was.
You could condemn it (and plenty of people did, even in a time when wives were literally the property of their husbands - many 19th C authors portrayed domestic violence with strong moral disapproval), but you couldn't change it. It took feminist analysis of the whole structure of the nuclear family, the law, and male-female power relations to give birth to the women's shelter movement.
Maybe in contradiction to others in this thread, I think having a coherent analysis of patriarchy is essential to feminism. Unlike radical feminism, liberal feminism never had one, and that's why mainstream feminism is in the mess it is in today. Having no clear understanding of why women are oppressed or the mechanisms behind it, liberal feminists left themselves open to corruption by anti-feminist queer theory, which is itself an unholy blend of postmodernism and libertarianism.
It easy to see the seductions of queer theory from a liberal feminist point of view: liberal feminists are aware that women are discriminated against, and they have a vague notion that this is because of our female bodies, but they are unable to go beyond the concept of discrimination to exploitation - to realising that the physical differences between men and women are the foundation of male exploitation of female bodies, and that exploitation itself necessitates the creation of not just formal inequalities but a totalising ideological system, which in the case of sexism goes all the way down to the construction of sexuality itself. That's why they try to pretend that pornography, for instance, has nothing to do with the perpetuation of male supremacy, why they try to cordon off discussions of sex and sexuality from sexism at all, and instead insist that women plaster on a grin and remain 'sex positive!' in the face of a sexual culture that is deeply negative for women and girls.
Thus, when queer theory came along to posit the seductive idea that femaleness itself was a fiction, which could be deconstructed linguistically and ideologically, they embraced that too, and now they accuse women who insist on the importance of the female body to feminist analysis of being the real sexists - because femaleness itself is obviously the problem, not male exploitation of same.
And that's why liberal feminists are ardently pushing laws that will destroy women's shelters (and every other sex-segregated space): they understand that the shelters are needed, but they don't know why. According to this non-understanding of male violence, one can oppose it, but one is forbidden to have a structural analysis of it, or indeed even to recognise that maleness and femaleness are material states, not identities. So we can see from this where 'feminism' without coherent analysis or critical thinking leads to: anti-feminism.
