Well, that makes sense after all abortion and smoking are so similar.
(snicker)
The acts are very different. That is why I am not a libertarian on abortion, while I am a libertarian on smoking. But the libertarian argument is the same: “I believe this act to be morally wrong, and I will not participate in it and I will teach my children not to participate, but I will not use the law to force my moral positions on anyone else.”
