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.

When you're in a stressful conversation of any kind - but especially about religious ideas - asking questions is a key strategy. Rather than working to have all of the answers (which isn't bad), it may be as helpful to learn to ask good questions.
A worldview is simply the way we see the world: where we come from, why we're here, and so on.
