There is a really great post on Ethnically Incorrect about how Muslims are raising their girls vs. how we are raising our boys. Deer and Wolves. Check it out, well worth the read.
For me this is an important issue. I think we are giving our boys especially the wrong message. We are letting the girls shoulder the responsibility of sexuality as teenagers (as in they are the ones who are obligated to avoid pre-marital sex) and then later letting them be the keepers of marriage by giving them the responsibility of pleasing their husbands.
How about instead of teaching our boys to be tough and our girls to be nice, we teach all our children to be pious, thoughtful, honest, loving and responsible individuals. The rest will take care of itself. Trust me if you give your children the love for the deen, and teach them to be caring they will be fine in their lives and their marriages.
Besides, if I remember my Islamic history correctly Khadijah had her own business and the Prophet (sws) was reported to have been helpful with household chores. So where did we start with all this other stuff anyway? It has to be culture, because we are all equal in the eyes of Allah (swt).
