Rumspringa

I recently watched a national geographics special called "The Devil's Playground". It is about Rumspringa, an Amish tradition that allows children ages 16 and up to have general freedom while still living in their family's home. They dress "English", own cars, have parties, etc. Some of these children (the ones featured in the documentary) go completely off the deep end and get into trouble with drugs, drinking, etc. But in the end, 80-90 % of these children end up ending their Rumspringa by being baptized into the Amish church.
While I don't always agree with the Amish (they're very anti-evangelism and their refusal to integrate electricity into their lives is admirable, though their reasoning -- not allowing physical connections to the outside world -- seems strange to me, why not be upset about roads if that is the case?), I have to say I really like this idea of Rumspringa. These children have been brought up with the ideals of the Amish church. They KNOW their stuff. Then, in order to give them an informed consent on what they would be missing if they stayed with their community, they are allowed to "run around" (the literal translation of Rumspringa). They get to decide for themselves, and the rate of people who stay with the church is a testament to the fact that Rumspringa works.
So why are we so afraid to do this in other protestant faiths? Many people leave the church in late adolescence only to return later. Some leave saying that their religion was forced upon them, that their faith never truly was theirs. Someone once told me that if I was brought up in a Muslim community I would still be a Muslim, not a Christian. But here's the thing about my family. We were never forced to be Christians. Yes, I went to a Christian school, but I chose whether I went to church. My parents allowed me to believe whatever doctrine I wanted (and still do, we have very different doctrinal views in some areas). I was free to explore different doctrines, and while my new discoveries were sometimes the object of arguments (I tended to be a bid firey about these things and confrontational about it), my family NEVER forced any ideals on me. So I think that I have had a very fair chance at deciding that what I believed was MY choice.
Rumspringa seems to be the Amish equivalent of letting children choose what they believe. I wish there was a way to do this in the "real world" but I don't see how. I think that people who are allowed to choose their faith are more likely to stay with it than those raised in a certain religion. Proverbs says we should train our children in the way they should go, but it does not say we should force them into that way.
