Let's say you are getting dressed in the morning and you have a shirt and a pair of slacks. You get dressed and go on your merry way. Well, what if you only had 2 shirts or 2 pair of pants? You would not be able to get dressed and would not go on your merry way. Something would be lacking and your outfit would not be complete.
Let's face it, men and women are different. They have different strengths and weaknesses - physically, emotionally, spiritually, and mentally. Their strengths and weaknesses complement each other to produce a whole. If in society we all try to be do the mens jobs, where will much of the compassion go? Where will children go who typically run to Mommy when they scrape their knee or just need a cuddle? There will be a big void and no one to fill it if we all try to fill a mans shoes.
If Mom and Dad both try to be in charge in the home it will create chaos, unhappiness, and confused children. In more traditional thinking, Dad is in charge and his word is final. I suspect most feminists would disagree here and say Mom should be equal to Dad, but sometimes there has to be someone to give a final word. If Mom constantly stands up for her rights and speaks her mind, what will the children do? They will end up just like Mom - back-talking and unhappy. While there are exceptions, feminism in the home just is not conducive to peace.
Traditionally women and men have different jobs around the home. I don't see this as degrading at all - just different. If we all try to take out the trash, who will do the dishes?
