I do not know what you believe, but I can pretty much know what you beleive if you answer the following question:
When does human life begin and when is it entitled to life?
It’s an ambiguous question. I personally believe life begins at conception and that’s an interest the state can take a role in from that point. They are entitled to life from the point of conception.
Though I can see how a person can rationally look at the situation and come to a different conclusion - saying that life, and the entitlement to life, begins upon birth.
It’s ambiguous and a person can come to either conclusion rationally. The more dogged advocates on either side are driven by emotion, and can’t clearly see the point the other side is trying to make.
