I think the problem is, as Dittany puts it, feminism is, by definition, political. And, as a corollary, she infers that all feminist research etc should come from the perspective of there being a patriarchal society. If you accept that, then at what point will feminists accept there is no longer a patriarchy? It does seem, at that level, to be a belief, rather than something based on research or individual experience.
I think that it would be very easy to prove the existence of a global patriarchy via independent research. Clearly, through much of the 3rd and developing World, women have a pretty bad time of it.
In the West (and my experience is really the UK and a little of France) less so. Women are doing better in education and in the 18-30 year age group, they are out earning men. Where I and a lot of feminists on this board will disagree is whether there should be a cost career-wise in women choosing to take time out for babies. I feel that someone with nine years experience of work (for instance) should statistically earn less than someone with seven years experience. Otherwise, it seems to me, you are discriminating against men, rather than trying to equalise things. Also, using board level comparisons is looking at a historical rather than a current patriarchy. I think everyone will agree that a woman in her 50s or early 60s will have experienced discrimination in the early part of her career (in the 60s-early 80s), and that will clearly affect her now. I think that if you were to take self selection (bright women who choose not to have a big career) and historical discrimination (as per my point above) out of the equation, salary comparisons would be very different.
I think both men and women have certain pressures on them to perform certain roles. However, in the West, it is relatively easy to choose different routes. At what point would the feminists on this board accept that the patriarchy (in the UK) had ceased to exist? What would be the test? And is it really feasible to expect no gender roles (even on a statistical basis) as long as women continue to give birth and choose to be primary carers for a period of their lives?
