Further, consider it on a personal level. If legally endorsing a father's right to protect saves lives...
Also, consider were it your own baby soon to be subject to the death-by-dismemberment of abortion...
Would you not feel in every fibre of your being the right, need, and obligation to protect your own baby?
The only way to correct the abortion situation is to grant human status (and thus the right to life) to unborn babies in the womb. Then the baby's right to life would trump the mother's wish to abort the pregnancy.
The reason we have legalized abortion is because unborn babies have no rights. It isn't a question of fathers' rights versus mothers' rights. It's a question of recognizing that an unborn baby is a human being with it's own right to life. BTW, as a single father who has fought hard for custody of my twin sons, I am more sensitive to and experienced than most in the ways of family law and issues of fathers' rights. As I said, I empathize with your sentiments. I just don't think your well-intentioned proposal is the right solution to this problem.
