The impending retirement of Justice Sandra Day O'Connor, confirmation of Justice John Roberts and nomination of Judge Samuel Alito has rekindled the debate over Roe v. Wade in ways that arguably haven't existed since 1992's Planned Parenthood v. Casey. Instead of changes to the existing law being mere conjecture or hypothesis, there is the possibility that the Supreme Court may (with the retirement of O'Connor and confirmation of Alito, and a case to actually work with) someday change the abortion debate in dramatic (or not so dramatic) ways. It goes without saying that the debate over abortion is one of the most contentious in politics today. However, what sometimes gets overlooked is the uncertainty and debate within each main camp (pro-life and pro-choice). The nuances of the abortion debate are something we should all keep in mind as we give our opinions on the issue, rather than relying on concrete, boring and cliché arguments that have been made countless times throughout the world and the web. Abortion obviously means a great deal to a lot of people, and so of course there is emotion on all (i.e. more than two) sides. Please keep this in mind as we discuss abortion itself, the law as it relates to abortion, possible changes to those laws and the political ramifications if changes are made to the law in the future. With that, I open version four of this discussion.
