It doesn't make you cruel and cold, it makes you principled. You choose not to visit the sins of the father on the child. You recognise that unborn children are guilty of nothing. Having said that rape victims who carry their babies to term are very special mothers.
They certainly are and I am sure will be richly blessed by Christ for their devotion to life. I think we can all agree on that
And this is precisely where Monomanical Anti-Abortion fanatics begin to go off the deep end and to offend the common sense and decency of most Americans.
Children do not have the legal right to say "no" to this situation in most cases. The parents (and you folks are among this group jwalsh) effectively force the teen child to live with the remembered trauma of rape for 9 additional months and to also suffer all the very real physical problems of pregnancy (including those unique to female teens).
You call this "principled" thinking, but in order to believe that you also must be opposed to all forms of capital punishment and indeed even the use of lethal force by law enforcement and the military.
You must be absolutely, 100 percent Ghandian in your opposition to violence, and you must apply that principle in all cases and not just abortion cases.
Do you? Are you?
That's the only moral pass you get. Anything else is naked and staggering hypocrisy.
