An acorn is not an oak. It is an acorn that has potential that it can become an oak with time and soil and sun light and water and the luck to be in a place that has all those things if a squirrel didn't eat it. A zygote is no more a human than an acorn is an oak. It is the potential to become a human being. 20% will be miscarried because there is something wrong with the fetus. Others will be still born. Yet others will be born in a condition that they cannot live. In most of the world the majority of infants will not see five years of age. To ignore the science and biology of conception, pregnancy, birth, and the fragility of new life is an arrogance I do not understand. In addition, the hubris of knowing where and when a soul becomes a soul is an obvious affront to the creator of souls. It is not unreasonable to deny that a zygote is a human being, not one whit more than to deny an acorn is not a tree. Mr. Schultz is correct in only on thing, there is no debate. There is only ignorance and an accusation of ignorance.
Let them have their forest of acorns, I'll take my forest of oaks.
