To ensure full gender equality in any society, women must have as complete control of their reproductive lives as possible. Attempts to determine that life begins at conception is simply an attempt to keep women in their place. If the right truly cared about the "lives" of fertilized eggs, would they not be trying to shut down IVF clinics as well? Or perhaps shut down the scientific endeavors being made using fetal tissue that could cure disease in adults and children? No? Are they perhaps only concerned with the "life" of a fertilized egg where it strips a woman of her autonomy and punishes her for having has sex in the first place, in contradiction of the mandates of the Christian god? There we have it.
