By Trent Horn, Catholic Answers - Unfortunately, there are many people who call themselves Catholic and yet believe, for one reason or another, they can be “pro-choice,” or support legal abortion, without compromising their Catholic Faith. When I say someone is “pro-choice,” I don’t mean only that he has voted for a political candidate who happens to support keeping abortion legal. I mean that person is committed to the idea that legal abortion is necessary and that he votes for laws and politicians with the intention of keeping abortion legal.
