Mothers are not held in higher regard (in our society) at all. They are vilified by large sections of the press for any and all decisions / family set-ups they are involved in. Fathers do not face this. And if they are a good parent they get praise heaped upon them, it is expected of women to be a certain way, and there is little help for those who struggle with it.
In our society mothers used to not have any "rights" to their children, then women and the children belonged to the man. This is still the case in some societies.
The thing is that for centuries men have sought to control women, through a variety of means detrimental to women, in order to control procreation. If men can procreate with no link to women at all, then for ones of that mindset it will be a right result. Use the women as brood mares and then have the children for themselves.
The disconnect of the word "mother" from anything to do with the female biological process that produces children is problematical. In a similar way that the removal of the word "woman" from anything to do with the female biological systems is problematical. In sexist societies how can it be otherwise. Women often don't have much, and are kept around for the things they are deemed to be useful for - sex with heterosexual men and having children. Start to cut pieces of that out and why are they needed? And yes I know it sounds extreme but in the Nepal situation we have newborn babies being airlifted out with their male parents and the women who just gave birth to them left in god only knows what situation. Disposable, I guess, which is poverty for you, but when that person's just grown a whole life inside them to be left by the people you grew it for just feels quite wrong. Because women have always been disposable haven't they, only important for breeding, historically and in many cultures. There are problems here, I think.
