Si certus es dubita
To be fair, for those for whom this is actually murder, and not punishing women for sex (in other words, for about 1% of anti-choicers) I have always thought that an exception for rape is a morally incoherent position. That would be like saying it is okay to murder an adult produced by rape.
I have always thought making an exception for rape is actually admitting that one's opposition to abortion otherwise is a confession that one hates the sexual agency of women.
