No-one is saying that men and women aren't different, just talking about where those differences come from.
I really don't think the OP is saying she regrets her daughter is a girl! In fact given the tone of her posting I don't think she desperately regrets naming her whatever name it is (correct me if I'm wrong OP!)
The way I read it was 'in the light of reading this profoundly depressing evidence that female candidates are routinely marked down / not called for interview etc., I do sometimes wish I had given her a unisex name to help counteract this' and yes, as I am reading that same book at te moment I can totally understand that thought process. I really don't think the OP is IN ANY WAY abdicating responsibility or encouraging her daughter to abdicate responsibility for her future academic or professional endeavors and I am at a loss as to how you are seeing that in her post.
My mother has an unusual unisex name and interviewers were often surprised when a 'dolly bird' turned up - she was also often the only female candidate there.
Ok so things have improed somewhat since the 60s but Cordelia Fine et al have shown that there is still a huge amount of discrimination against women in a professional context.
exoticfruit and others, I really do recommend the book. It talks a lot about the ways in which men and women are different (and the ways in which they are the same) in a very accessible and interesting way.
Plus the cover definitely doesn't have a picture of a hairy-legged man-hating feminist on it or anything that will stop boys fancying you on the tube I PROMISE
