UnDF'd...YES!!!
In that study you posted, it was a consensual, albeit illegal, relationship. The girl was scared, and needed help. It happens every day. When I was in high school, one of my best friends had an abortion after being impregnated by a 27 yr. old. We were 15 years old. She doesn't regret it, 6 years later.
Women are finally able to go to a clean, safe, clinical surrounding to have an abortion. If abortion is made illegal, it will still happen just as often. It will just be unsanitary, unsafe, and potentially deadly. If you've never seen the first "If These Walls Could Talk" movie about abortion, go rent it.
Planned Parenthood also does much more than just abortion. They provide contraceptives to women who could otherwise not afford it. They have clinics in poorer countries to provide free pre-natal care, and sex education to women and girls who do not otherwise have access. Currently, they are working to get contraceptives covered on health insurance.
So, yes, I am still a huge supporter of Planned Parenthood.
