You've actually answered my questions in your own post #36.
The semantics of the debate doesn't matter. The abortion question for rape/incest victims simply shouldn't be answered by Republicans. Get back to the old "no comment", stand your ground on being pro-life, and let the interviewer pound sand. It's a difficult question, but at the same time, it's simply gotcha politics that reinforces the leftist narrative that Republicans are too extreme on abortion.
Nevermind that rape/incest, as I've stated before, is statistically minuscule in the total number of actual abortions and is simply an out used by liberals to maintain the abortion status-quo.
