1. Human life begins at conception.
2. Big deal.
Even though I do not object to legalized abortion, it has always irritated me when people arguing against abortion prohibition would not admit that, yes, they thought it should be legal to terminate a human life.
The Catholic church is right about this: if you believe that human life is sacrosanct, you can not tolerate abortion, euthanasia, or capital punishment.
If you favor any of those listed, you are speaking against the absolute sanctity of human life, and saying that different human lives have different values. You are saying that you have to think.
Live with it.
To me, abortion is ending a human life, but it is not murder. If it were done without consent of the mother, it would be a grave crime against her, but the interests of the fetus are not the interests of our society. Certainly people who are infertile and would love to have a baby, other relatives (or perhaps boyfriend or husbands), and people generally opposed to abortion may find this disturbing. That's OK - go ahead and bribe the mom and try to make it worth her while to have the baby, but in the end it is her decision.
To me, euthanasia should be a basic human right. If you do not believe your life is worth the pain that it costs, you should be able to end it. The fact that you might change your mind later is really not the issue....you should have that right.
As capital punishment goes, I am sort of against it. A healthy human life must have some value, and ending it against the will of them who would live it seems wrong, a waste. But in the really bad cases, it does not seem much of a loss. I guess I would say that it should be avoided when possible.
