If you want to delve into stem-cell research, be my guest, because I've already won three debates on stem cell research.
Anyway, here goes for the third time:
You can argue in favor of abstinence all you want, and how teenagers deserve shame, and whatever, you can present your ideal world where when people aren't ready for children they don't have sex and where pregnancy never threatens life, etcetera. I'm presenting the facts. When abortion was illegal, young girls were dying of vaginal infections. Today, abortion is legal, and young girls aren't dying of vaginal infection.
Morality is a disease, here's why: it is a word the self-righteous use to push their ideals no matter what the results are. It's a word that kept people spreading lies about condoms in Africa even when they helped spread AIDS. It's a word that people used to justify burning people at the stake for what they believed.
Abortion was a cure, and I already said why. It seems so clear to me, girls aren't dying by the hundreds because of vaginal infections today. You can argue whatever you want against them, but people do get pregnant that don't want a child, and will continue to.
Also, an embryo is not a human being. An embryo is a living organism in one stage of existence before it becomes a human being.
