Every child deserves equal opportunities. Why should a male child be celebrated but not the female? The world is changing. Today's woman expects her husband to share in the household duties. She expects him to spend time with the children. Women are going out to work, to chase their dreams. Daughters as well as sons should be trained at home to adapt to the realities of today. My sons help in the kitchen, even as young as they are. Their toy box contains dolls as well as trucks and building blocks. My friend's daughter got a toy workbench for Christmas.

Now isn't that an awful thing? A girl would be retained by her father to procreate and give him an heir. Tess Onwueme tackled that subject so well in "The Broken Calabash" Isn't it fantastic to have grown out of such traditions? I don't know which was worse, that or the killing of twins back then.
 
Now, I find the Belgian nuptial system fascinating, since as a couple both family names are linked, example "Vandenhoudt-Unigwe." Truly Fascinating! That is bloody perfect, is it not? As both parties acquire a family, and no risk of the loss of family name. Would you know how that came about?  

I agree that it is an awful tradition but some people posit that it is liberating for the woman: no marriage but condoned sex. I do not know about that. I have a few Unigwe relatives whose fathers are not Unigwe!
As for the history of the Belgian system, I could find out. However once a woman is widowed or divorced, she may no longer use her husband's name. My grand-mother-in-law started life as Maria Smekens, then became one half of the Branders-Smekens family, but died a Smekens.

Oh forget it. The system sucks then. Let's go back to writing. Why is it that more women writers tend to focus on the liberation of women and equality with men, rather than on works the foster family values and the need for strong family units? Should women write more family feel-good fiction and poetry or are these a bit utopian in our modern world?

Let us take the example of Nigeria. Earlier literature by Nigerian men from Chinua Achebe to Cyprian Ekwensi created women as either rural docile wives or urban whores. In Achebe's "Things Fall Apart," Okonkwo's wives dare not talk back to him. Ekwensi's "Jagua Nana" is a good-time girl. Look at the Onitsha market literature and its portrayal of Nigerian women. Men had the upper hand in writing because they got better educated. Igbo communities sent off sons on scholarships abroad but taught the women the essentials of domesticity, how to be good wives for the new elite men.
When Nigerian women started writing, they wanted to reverse those images. They wrote counter-discursives to the males' works. They had to undo many years of damage to the female psyche. This is the reason why many women are focused on liberation and equality matters. Another reason, I believe, is that many women writers think that by writing the sort of fiction you have just proposed, they will fall into the trap of writing what society expects a woman to write. We want to write ourselves out of stereotypes that have been hung on us for many years. African (especially Nigerian) men, according to Ogundipe have been "weaned on centuries of male domination (and) will not willingly relinquish their power and privilege" By focusing on women's liberation and equality of sexes in their works, women writers are trying to balance the power structure. For (us?), writing is an act of righting. There will be time enough to focus on other issues.
I think every woman, every writer should write what (s)he feels comfortable writing, what she is passionate about. However, as an Igbo woman living in Belgium, my passion at the moment is the drawbacks of being an African woman in my particular society as well as the experiences of my sisters, and my friends, in their own communities.
