My Flawed Abortion Logic

In answer to a letter I received regarding my statistics on unplanned pregnancies and failed contraceptives leading to abortion, I must admit the following: The letter writer says that I used bad logic and he is right. I do apologize for misleading my readers -- I did not intend to do so. I understand that my percentages and statistics were off -- instead of 100,000 Canadian abortions it was only 97,000 or even as few as, thank goodness, 93,000 as he states. And it is true that my failed contraceptive figures were convoluted. However, the fact is that only a small percentage of pregnancies result from failed contraception so what about the rest of the pregnancies?
