I don't disagree with you, it's a complicated moral issue, I do not advocate for using abortion as birth control, but forcing women to birth and raise children when they can't afford them or even do not want them creates a lot of problems for those children down the line.
Mindlessly breeding people into poverty is no more humane than aborting a clump of cells.
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.
