To restrict a woman's right to choose is to deny her rights as a woman. This is a self-centered reason. That the woman has a responsibility to protect and guard life. That it puts the woman's personal interests and comfort above the value of life of the baby. That it is not denying a woman's rights anymore than she does not have the right to murder, steal, or lie.
Rights come with responsibilities.
Choosing to kill another is a great responsibility that needs to be taken seriously. This is why we have trials. However, in the womb, no trial is necessary, just the desire of the mother. There are too many people in the world. Besides, if the number of people is the issue, maybe they should start getting rid of the sick and old.
