With American fertility rate at 2.1, nearly every single adult American and nearly every adult in the entire developed world for that matter, is limiting God's greatest gift. Conception is not a magic word. It's just a word. Abortion's final outcome is no different than that of family planning. They both reduce the number of people. Family planning, tenfold to that of abortion!
My opinion on this subject is that unless you have 12 children and you're a woman, you should not throw stones because you are effectively doing the same thing, just doing it cleanly. Instead of hunting for your food, you're buying your chicken in a cellophane wrapper at the grocery store. It doesn't matter how you get it, you are still killing for your own personal needs.
I recognize this is a hotly contested subject and you may not ever believe as I do. I'm just explaining my thoughts and why I feel anti-abortion is the most hypocritical opinion in our modern world, due to the reason I have just communicated.
