I think there is a debate of when ‘life’ happens. And that more or less everyone is against removing life that has already happened (directly, not in an underfunding school nutrition and living wages sorta way). So the side that believes life happens at conception is literally removing choice from those that believe it happens at birth.
Ironically, many advocates of life at conception also are against sexual education and universal birth control, or in favor of promoting that abstaining from sexual relations should be the solution. This context makes it more about governing how women make choice regarding their bodies (in sexual manners and in conception manners) and largely insult men from those same consequences.
Please note that the law makes not allowance for incest or rape- so if one was a victim of these crimes, they would still be required to carry and deliver the child. A child in the case of incest that is likely to be genetically mutated such to lead to a life of suffering (for the child and those caring for them).
