"How is contreception a threat to babies?"
Contraception isn't a threat to anyone who doesn't exist. Most chemicals and methods of birth control are FRAUDULENTLY marketed as contraceptives, meaning they prevent sperm and egg from ever meeting. If sperm and egg never meet, no baby. Are you with me so far?
"Most contraceptive prevent the fertilzation of the egg. No fetus ever exists."
"Contraceptives" sometimes prevent the fertilization of the egg. Abortifacients destroy the new human being.
"If they abort a fetus in the first three months of pregnancy it is not killing a baby human. It is killing a fetus which has the potential to become a baby human."
I've given up on trying to argue with people who don't accept scientific fact and instead wallow off into some philosophical and theological quagmire of their own making. A distinct human organism is formed at conception. Read a biology textbook.
"I think the only real threat here is to those who want to limit the freedom of women to control their reproductive functions and thereby keep them enslaved to an outdated morality."
Feel free to reproduce. Feel free not to reproduce. But when two genetically distinct human organisms mingle their chromosomes, they create a new distinct human organism. At any point after conception, we're no longer talk about reproduction, since the reproduction has already occurred.
And it is not now, nor has it ever been, moral to intentionally starve an innocent human, in any stage of his or her life.
Mm hmm-a distinct human organism, but not a baby. Big, big difference.
