Even if you discard the moral argument for a moment, this is still shocking when you consider the implications from the parental rights angle. This ruling further erodes the notion of family, eliminating the parents' role in raising their kids, transferring it instead to the State with all their wisdom.
Morality step back in, and what you have here is an excuse in a bottle. The easier you make it for kids to do whatever they feel like, the more often they will do it. No risk, no consequences, easy fixes. Why not?
The hoops that I as a parent currently have to jump through just to get an asthma inhaler kept at my kids' school for emergencies are there by design to keep them safe, keep the medicine from being abused (intentionally or unintentionally), and so that we can be notified by their medical staff whenever it needs to be used. But if a "13 year old can purchase a powerful hormonal drug that can almost quite literally rip out her uterus lining without anyone ever having to know about it" that's just fine and dandy.
A 7-year-old can be suspended for making a Pop Tart gun, and his 12-year-old sister can get the pill whether her parents like it or not. -
