Abortion is a deadly business, destroying people in the near term, and more people in the long term. There are alternatives to abortion that are better for both the mother and the child.
Wrong and inexcusable
Destruction of the embryo in the mother’s womb is a violation of the right to live which God has bestowed on this nascent life. To raise the question whether we are here concerned already with a human being or not is merely to confuse the issue. The simple fact is that God certainly intended to create a human being and that this nascent human being has been deliberately deprived of his life. And that is nothing but murder. — Dietrich Bonhoeffer, quoted in Bonhoeffer: Pastor, Martyr, Prophet, Spy, by Eric Metaxas
As people try to rationalize and excuse it, they undermine civilization:
The irony is that modern liberal democracy needs religion more than religion needs modern liberal democracy. American public life needs a framework friendly to religious belief because it can’t support its moral claims about freedom and rights with secular arguments alone. In fact, to the degree that it encourages a culture of unbelief, liberal democracy undermines its own grounding. It causes its own decline by destroying the public square’s moral coherence. — Being Human in an Age of Unbelief, by Charles J. Chaput
It’s so obvious that people forget: death is bad. Abortion is all about death, and nothing good comes from it.
