tesla, you missed the main point Orangey was highlighting (see bolded), you again responded to her by talking of 'feminism' as if it is in one unifying term/ideology, when, in reality it is not the case.
What exactly is this feminism that you talk of?
And, if by feminism, you mean advocacy for equal rights for women in today's society, then, no, it is not obsolete, unless you think of it in terms of a selfish, "I"-centered view, of white (or whatever other priviledged group you belong to) middle-class women in America. It'd be more accurate, to point out that in your tiny bubble of associations (your social position), it is obsolete.
Those, like myself, who identify with certain feminist theories, are not just advocating for the rights of white middle-class women, but, women in all segments of our society. And, extending that bubble further, advocacy of women's rights internationally too, qualifies certain feminists theories today(even if I am sitting comfy in North America), and the need for such advocacy.
There are still huge social barriers, with regards to women's rights, in certain African American communities, in Aboriginal communities, in immigrant populations, in low socio-economic communities, and yes, these are still ongoing, currently, in North America. You should be less rigorous with your inclusion criteria.
So, to paint all women in North America, by the white middle-class brush and then use that as the premise of why certain theories of feminism is obsolete as a whole, is, as Orangey pointed out, reactionary and short-sighted.
