Great tagline! I finally read one that my own doesn't have an answer for.
your tagline is similar to the argument I put forward when anyone wants to debate abortion. I'm against abortion as birth control (other circumstances have different moral questions - I can understand, even if I don't support, abortion as euthenasia in the case of hopeless birth defects (hopeless=won't live after birth)). I simply set up a simple "if I'm wrong" vs "if you're wrong" question. The pro-abortion folks don't like my reasoning and usually leave in a huff.
