Strange to say, it has been my pleasure of late to engage some anti-choice adherents in spirited discussion of the nature of human biology, pregnancy, birth, and the definition of a human being. I use the term "discussion" rather than "debate," for to be a debate, there has to be some agreement upon the basic grounds, and that is where the discussion of abortion breaks down, because both sides have very different definitions of what constitutes a human being, or a baby, or development. This is what hampers any attempt to find common ground. In the end, the discussion is more about biology and belief.
