Abortion is, simply, the unnecessary killing of an unborn human being. These articles were not written to shame anyone who has had an abortion, but to shed light on the facts about the unborn, on the consequences of abortion, and on the arguments made in favor of killing babies for convenience.
Abortion is always a hot topic. Some see the debate as between religious people and non-religious people, but that's hardly accurate. There are a lot of atheists who oppose abortion, for example. The question at hand is whether abortion is a moral good, a moral evil, or a neutral act.
