Your document stated "The morning-after pill works by preventing ovulation or fertilization. In medical terms, pregnancy begins when a fertilized egg attaches itself to the wall of the uterus. If taken within 72 hours of unprotected sex, it can reduce a woman's chances of pregnancy by as much as 89 percent."
But as you can see the definition of both pregnancy and abortion do not match up with what these people are claiming. In fact it is not an abortion pill because it does not do anything to a fertilized egg it simply prevents the egg from being fertilized in the first place. The definition of abortion is "expulsion of a fetus.." which in fact even if the egg where fertilized it still would not become a fetus for much much longer then it takes for the pill to have any effect. Not to mention that the pill does not have any effect on fertilized eggs all it does is prevent the egg from being fertilized so if the egg is fertilized and a women takes the morning after pill it will do absolutely nothing.
