The reproductive rights organization did not support past attempts at imposing age requirements for marriage because of concerns that it could set a precedent that undermines minors’ rights to seek abortions and other sexual health care.
That's interesting, and it is something that seems to keep coming up in this context. Which is to say, there is potentially a disparity around three elements here: the legal ability to consent to sex, or practically in most cases it's really just adult acceptance of sex among minors; the legal ability to consent to these kinds of sexual health care, which presume that the minors are in fact having sex; and the legal ability to consent to marriage, which historically is a way to manage the consequences of sexual activity.
In a way, the concrete substance of marriage has really been the existence of children which tie together the mother and father with all kinds of obligations, pretty much permanently. So as soon as young people in a society have been sexually active, they have generally been allowed to marry. So one disparity is, if you can consent to an activity that could create a baby with someone, can you not consent to a marriage contract?
Then the other is, if a minor is too young to be having sex at all, and they seek contraception or abortion, then they are at best a child who is at best doing something so serious that it is illegal, that parents should be able to address, and it may be they are being sexually exploited. So is it really the job of health care providers to decide that everything is ok without the parents? We all know this is the argument being made for schools and doctors helping kids transition without parental involvement - even with no evidence the parents will be a problem.
I think a lot of this came about during the permissive period of the 70s and 80s where people seemed to think that birth control had solved the problems of early sexual activity - that is, teens and even young teens could be open and sexually active and it was fine because access to bc etc meant it was risk free and natural, even with an older partner. Many people really thought even quite young teens could consent to sex, and especially among political progressives. They had little or no worry about these kinds being exploited and would have pushed the age of consent much younger. Planned Parenthood absolutely thinks that way.
i think these issues are going to keep coming up.
