The final outcome is that regardless of where you stand on abortion...part of your money paid will be supplied to pay for abortions. If you can live with that, great. Since there are those who believe that abortion is nothing more than legalized murder, part of the insurance money that they pay will go to pay abortions against their own personal beliefs.
If I were a part of that group, I'd have a heck of a time justifying my money paying for the murder of a fetus. And since no one cares how far along its development is, some would call it a term fetus or a baby who would otherwise survive outside the womb. Money for irresponsibility...great value !
