Given all the (justifiable) hoopla surrounding Obama's "contraception edict," I'm surprised I haven't heard more discussion about the nature of contraceptives themselves. Both common sense and the English language conspire to give most people the impression that the word "contraceptive" has something to do with preventing conception. Unfortunately, the courts ruled (in the '80s, I believe) that "birth control pills," which function by preventing a fertilized egg from implanting in the uterine wall, can also be defined as contraceptives when in fact they would more accurately be described as abortifacients. Many, if not most, of the "contraceptives" being sold today result in "birth control" only because they take the life of an innocent human being.
