Being pro-choice is NOT being anti-human. It is not anti-birth. It is not anti-life.
What you need to understand - so I'll write it slowly - is this:
Pro-choice is pro ALL choice.
If you want a baby, that is your choice. Go do it. If you want to abort, that is your choice. Go do it. If you want to give to adoption, that is your choice. Go do it.
As far as animal rights go, I am also very strong for reducing cruelty to food-animals. There is senseless violence to born, living, conscious animals and there is no excuse for it.
I'm not anti-meat, not at all. We are omnivores, we have stomachs capable of digesting meat, bodies made to run off of those nutrients, and teeth that can remove the meat. I am anti-cruelty.
On that note, I often see abortion as preventing cruelty. It is cruel to bring an unwanted child into the world. It is cruel to force a woman to be pregnant when she doesn't want to be.
