There's nothing convenient about asking a woman raped against her will to carry to term. If a 12 year old child gets raped by her stepfather, by the grace of your god, you'd have that young child carry that with her.
You have no morality, you just pretend to because you believe a book absolves you of responsibility. "Well, I don't know god's plan, but I'm sure the 12 year old will learn something from this". That's not morality, in any sense of the word.
Thankfully, and I do mean this, the population of non-believers continues to grow so we can eventually unburden ourselves of such nonsense and make decisions based on sound logic, reason and science.
