Planned parenthood's purpose is not to perform abortions on teenage girls without gettting parental consent.
Planned parenthood does provide basic female healthcare to lots of women who couldn't afford to see a doctor otherwise. They provide pap smears to check for cervical cancer, they check for STD's to prevent the spread of diseases, they provide birth control (which is not covered by insurance, by the way) to women who don't wish to have chidren but cannot afford $50-$75 per month for birth control. And, it does provide pregnancy termination services.
What you need to understand is that everyone in this country is living a completely different experience. We are all individuals with individual needs. Some women are faced with making a tough decision and make this decision based on what is best for her situation, not yours. Some young girls come from abusive households and alerting thier parents to a pregnancy or planned abortion would put their lives at risk. Not everyone has a good family. Not everyone has a loving home. Not everyone has a support system. If you do, then you are blessed. For those that don't, we need to have compassion.
Planned parenthood gives women the ability to decide what is best for their own body. There should be more support for such a wonderful organization.
