This has been the usual argument during all times when it comes to holding back women in the society. Although it is true that originally the biological differences led to a division of tasks between men and women, I do not think that it is a good argument to apply today. I do think women do want a career as much as men do, but that traditions and expectations keep them back (as well as let society hold them back). What I mean is that we now live in a civilized world where there is hardly anything to gain from giving men and women certain roles in society. Note my emphasis on that the western world repression of women do not lie much in the laws themselves, but that it has a traditional origin.I see it as acceptance of a biological fact.
I agree, and I have never said there are not more important issues to deal with. All I am saying is that repression of women in the western world is still a problem. The case of repression of women explicitely stated in the law is of course much worse. This does not mean one cannot fight both problems at the same time though. (Probably a progress in one place will also help the other.)But I think you should keep things in perspective. There are far more serious issues of oppression and inequality confronting women than work and pay conditions in Europe.
