Being a mother and a wife isn't wrong or doesn't make you "second class". But it all depends on what being a mother and a wife means for these ultra conservative schools. If being a wife means being a married woman who's still free to be herself, do what she likes and speak her opinion then it's fine. If being a wife means being submissive, having no saying in the home, being ruled over by your husband and treated like you're one of the children, playing to role in making the decisions and obeying your husband whether you want it or not then yes there is something wrong. The thing is that these religions often teach the second definition of a wife to their girls and in these case they are being treated as second class children.
The problem with raising boys to be fathers and girls to be mothers is that it promotes the gender roles and doesn't allow men and women to be who they want to be. What if a boy really likes being with children? Why shouldn't he have the right to stay home without being ostracized or humiliated by the society? Same for a woman, what if she wants a career? Or what if they just don't want any children at all?
I think that we should examine the whole problem clearly and not just blame everything on feminism. The divorce rate increased and the marriage rate decreased, yes, but why? And does the fact that there were less divorces before prove that previous marriages were really happier? We must not forget that before, when a woman divorced, she lost everything, the home, the children and since she was economically dependent on her husband, she had to go back to her parents (if they didn't reject her), she always had to be dependent on something, besides they were raised in such a way to believe that husband had the right to rule over them and that they were bad if they divorced no matter how evil their husband ever could be, it was quite like what the muslim women face today. In this case, these women had to remain silent and continue the marriage even when they weren't happy. As for the husbands, they were practically never home so they weren't really as involved with the family life as women, women tend to feel it and realize it earlier when the marriage is not going okay anymore, that's also why there are more women filling for divorce than men. So yes, the marriage rate is decreasing, but that does in no way prove that the previous marriages were happier.
That is why we should put an end to the gender roles, why not let the families decide themselves who's in charge instead of automatically giving that role to the man? Why not let the family chose who cares for the children instead of automaticlaly giving that role to the woman? Not all women and men agree with their gender roles, in the end all the men and women who decide not to act the way the society wants them act end up pressured and lonely.
Though i find it saddening that raising children is seen as "second class", in fact, practically anything feminine is undervalued in the society, only what men do is seen as important and hard. In the end, the only way for women to be recognized is by acting like men. And the only way for "feminine tasks" to be valued again is by making men perform these tasks too.
* sigh, really saddening...
