I wonder what would have happened if the Old Americans had emplyed this thought process to the slavery matter. “Since we all disagree about the personhood or lack thereof of these slaves, why not let each family, slave-owner, and their pastor each make their own choice about whether or not to keep. kill, otherwise mistreat slaves?” What if the same had been left to the Germans to decide for themselves regarding the humanity of the Jews of Eastern Europe in the early 20th Century? While I might agree with you as regards gay marriage, abortion is a question of whether an individual being denied all rights, including life/existence, simply based on other peoples’ judgment that he is not “fully” or “truly” human should be protected. Since science cannot tell us when humanity can be said to be fully extant in a baby, the law ought to protect the entire life of a baby, from conception to senility. No arbitrary categories should be placed at any point in between to determine what we humans cannot.
