I do not support the philosophical foundation of Planned Parenthood nor some of their operating methods, although I do believe that accurate information and counselling should be available to young people.
I don't support publicly funding an organization that doesn't present a well-rounded perspective of health risks of some birth control, the emotional impact of abortion, and doesn't feel guardians/parents of minors are a part of the equation even though they are legally responsible for all other areas of the child's life. If someone is old enough to engage in sex, they also need to be counselled about the responsibilities that accompany sex, including purchasing their own birth control, talking to a doctor and to their partner, getting tested, and having an effective plan for what they would do should they become pregnant. Sex is a privilege rather than a right and it is accompanied by adult responsibilities that most children are not equipped for. In some cases, I believe we are also setting a young person up for more exploitation by providing these resources for free.
While I am aware that some pre-teens/teens will engage in sex anyway, I would prefer to put resources into information that would help them make a more informed choice, education that would give them stronger communication skills and choices in life, and in more familial supports that would prevent children from cutting off their options at an early age or seeing having children at a young age as an attractive option.
From the time I have spent working with troubled teenagers, my experience has been that the reasons for engaging in sex at a young age or having children at a young age have very little to do with the availability of birth control, or in achieving real sexual pleasure. It usually has much more to do with a lack of communication skills and assertiveness, looking to someone to supply emotional needs (which family/community is not offering) through sex, norms in their subculture, needing something to love or a lack of options/hope about the future.
By addressing these issues, I believe we would see a decline in STDs, pregnancy rates and abortions and our resources would be channelled into preventative measures rather than reactionary ones.
