You mean like Mitt Romney did in the South Carolina debate when being asked about his tax returns?
US election 2012: Mitt Romney booed over tax returns during South Carolina debate
Moreover, no matter how statistically likely this phenomenon might (or might not) be, it is absolutely certain not to be universally true. Hence, to pursue a policy based upon that uncertain likelihood is to guarantee perpetrating an injustice upon an innocent victim, that she is somehow culpable for the pregnancy due to rape.
What in God's name are you talking about? Did you listen to the interview? He said nothing of the kind. His policy is not "based on" this science, he mentioned it only in passing, and he expressed that rape absolutely can result in a pregnancy. And are you saying that it is an "injustice" if a woman does not abort an innocent unborn baby? That's disgusting. Abortion has NOTHING to do with "culpability." Only liberals like Obama think a baby is a "punishment." Abortion is about the life or death of an innocent unborn child and nothing else.
Your obsessive ideology has blinded you to the point that you cannot read. I said that his statement (implying that a woman's body rejects semen in forcible rape) places confers upon those women forcibly impregnated by that means a stigma of culpability. That would be unjust.
