Sex-Education in Schools

I was reading the paper the other day when I cam across a story about a middle school in Portland, Maine that will let middle school kids (ages 11 to 14) pick up birth control pills if the have a waiver that is signed by the parents. Once the waiver is signed by the parents they are not notified if birth control pills are used. Now to me it was a little disturbing, that birth control pills would be handed out to middle school kids and not tells their parents about it. I later found out that the reason for putting this measure in place was there were about 3 to 4 cases of kids getting pregnant at this school.
So I can sort of see why the middle school is doing this, even if it makes me uncomfortable, but the thing I don't get is why the parents are not informed, call me old fashioned but if there is need for a 11-14 year old to use birth control I think the parents have a right to know. Until a kid turns 18 they effectively belong to their parents unless they are emancipated. They can't be sued, they can't vote, so why can they take birth control pills without their parents knowing.
The bigger issue here thought is one of sex-education. Let me give you a little personal background. I was raised from a very early age that one should not have sex until marriage, I was also taught not to disparage someone who held a different view on sex. Now it didn't matter if my school taught me abstinence-only sex ed or safe sex use sex-ed I wasn't going to change my views. I think more parents need to stop relying so much on the school to teach sex-ed but instead teach their kids at an early age (not to early) about sex and all the responsibilities that come with it. I'm not saying get rid of sex ed in school altogether but it should not be the primary source of where these kids learn it. Parents need to be more responsible for their kids.
