I understand why they say contraceptives and other birth control is sinful. But it is most definitely the lesser of the two options, and the third: abstinence, is popular with about 5% of the teenage population (I did an anonymous study in bio class. Apparently 30% were still virgins (at 18/19 age), and many of those were virgins due to their belief in abstinence whether for religious or health (STD) reasons). I'd much rather tell someone to use a condom then to tell them that abortion is an option at all. I do believe that life begins at conception. I personally don't understand why anyone wouldn't. The baby is going to be a baby in 9 months, unless you do something to halt that progression.
I'd much rather everyone practice abstinence and simply not get pregnant if they don't want a kid, but (atleast on this topic) I'm slightly realistic and understand first hand that abstinence is THE MOST difficult form of birth control to keep. So I know that it won't work for everyone and thus teaching other forms of birth control is necessary. (Birth control is preventive, abortion is not birth control.)
I'm against abortion, but I'd rather the baby never have to experience such a horrible life as it probably will if it's unloved.
In my opinion Catholics and Protestants, Christians, should take up this view because it is my belief that God saves these babies, and this belief is backed by scripture.
