You have nothing to apologize for. And while medicine is a constantly evolving field, I also think that's one of its virtues. Things change as new information is gathered. If there comes a point in time with emergency contraceptives are considered an abortive measure by the medical field, I'll change my opinion on it. Until that time, I agree with the current definition of abortion. That is, the definitions both you and I gave concerning the removal of an "embryo or fetus." Nothing in that says anything about a fertilized egg or blastocyte. Before the embryonic stage, it doesn't fit into the current medical or legal view of abortion.
