It seems to me that this thread is highlighting one serious problem with evolutionary biology, which is that is that it is so prone to being misunderstood, particularly with regard to the fallacy that it implies biological determinism (eg the "men can't help themselves" thing.)
Despite Etin's and Monkeytrousers' numerous explanations (I particularly liked Etin's recent explanation of distal and proximate causes), the thread is still full of posts from highly intelligent and well read women who are rejecting evolutionary psychology on the grounds that they see it as a justification for the status quo.
I don't see why there should be anything controversial in investigating why certain behaviours might have persisted over thousands of years and over almost every human culture. Surely we have a better chance of changing behaviour if we understand all possible motivations (proximate and distal!).
It looks to me as though some of the debate in this thread is more to do with lack of understanding of basic concepts in evolutionary theory than with any real difference in ideology. We're all feminists. We all want women to have more control in society and in our personal lives. Looking at the imbalance of power between genders through an evolutionary lens gives us the chance to come up with a deeper understanding of the problem, and I've always believed that understanding a problem is a crucial factor in finding a solution.
However, I agree that the question of how the understanding of evolutionary biology might be applied to the here and now is a complex one - especially because it is so easily misunderstood and misappropriated.
But for starters, and to reiterate my earlier post (and to echo Griet Vandermassen), it's got to be a good thing for feminist scientists to actively engage in this field to counteract the male bias inherent in previous interpretations of evolutionary theory.
