Okay, I may have read your tone too narrowly. I appreciate the courtesy either way. Thanks.
Rape and incest are very difficult calls, obviously, but I would hope that as a culture, we're not using those rare exceptions to justify a rule that is abused in a supermajority of other cases that are not close calls, morally.
You can choose not to get pregnant, but if YOU failed to behave in a way that fits with your preferred way of life, we shouldn't take that out on the baby. Be a big boy or big girl and live up to your responsibilities, and if you are unable and/or unwilling, there is an oversupply of capable, willing, loving families who would adopt the child you don't want. Do you make an exception for rape/incest? Morally, I could see it, but if you draw that as the line of demarcation you're going to get a lot unfounded allegations borne out of convenience. That's tricky.
Bottom line: You can't morally end a life in the name of convenience, and if we're being honest, that happens every day in every city in America, and there are lot of otherwise smart, wise and otherwise moral people who are turning a blind eye to it. Sounds pretty familiar to any decent student of American history.
