Ridiculous. A fetus is not a person. A pig or a cow is more sentient. If we're going to call a fetus a person, first we gotta do intelligent livestock and outlaw killing animals for food.
The difference is that most Americans would be outraged if the government forbade them from eating meat, because that takes away their freedom and forces them to spend slightly more money on food that doesn't taste quite as good. It astounds me that these same people think the government should have the power to force someone to give birth to a child they don't want and can't afford. The amount of suffering that will cause is unimaginable.
Of course, most people who are against abortion won't hesitate to get one if they or their daughter needs it. It's always different when it's your life and dreams that are about to be destroyed.
