This article brings out why abortion is ultimately a religious issue.I am going to have to disagree with you. Abortion is a moral issue, but not a religious issue. Atheists can know that abortion is wrong, as some do, just like they know stealing is wrong.
Atheism is a metaphysical viewpoint that assumes the non-existence of God and, in most cases, the non-existence of reality beyond the physical universe. OTOH, religion assumes the existence of God or at least a supernatural existence. Both the atheist and the religionist derive their beliefs relative to murder and other moral and ethical matters from their presuppositions, which are tied to their metaphysics. Atheists believe they can derive their positions on right and wrong, or even if "right" and "wrong" are valid concepts, from their observations of the material universe interpreted by reason. Religionists believe that at least some areas of right and wrong may be derived from books they regard as being divinely inspired. Atheists disagree widely on many moral issues. Karl Marx, Friedrich Nietzsche, Ayn Rand, and Jean Paul Sartre have sharp disagreements on many issues beyond their shared metaphysical views. The same could be said of Muhammad, Maimonides, Calvin, and Gandhi.
You are correct when you say abortion is not a religious issue. However, you cannot divorce anyone's position on the matter from their metaphysical viewpoint.
Abortion is a moral issue, but not a religious issue. Atheists can know that abortion is wrong, as some do, just like they know stealing is wrong. You're right, but I think he meant to say "It is NOT a political issue, it is a moral issue," which is an accurate statement, as is "abortion is murder," and as is "All of us by virtue of our not being incarcerated or killed in an illegal act to defend the unborn, are willing accessories to murder." I think anyone who is pro-life..and not a hypocrite, would agree with the stark reality of that statement. Think about it.
