As an aside, read this portion of a report into the Silver Ring Thing:
The American Silver Ring Thing campaign to promote sexual abstinence has a failure rate that is alarming, 88%, made worse by the fact that when they did succumb and have sex, they were 20% less likely to use a condom, hence risking both pregnancy and STIs, the very things it sets out to combat. It is very worrying that the worst sexual advice for teenagers from the country with the worst teenage pregnacy rate is being imported to this country,which already has a serious problem.

I disagree that this is not about religion - it's a system rooted in evangelist fundamentalist Christianity - so I think that the girl in question just may win her case. The fact that she may actually alarms me.
