In principle you are asking a good question here, but what fascinates me much more on this topic is just how allergic some people react given the idea that a 16 year old girl could question their morality.

Because this is what it always boils down to: figures like her act as a mirror and many people don't like what they see in it. And it is easier to attack the mirror than dealing with what it tells you.

She hasn't questioned my morality, though.

I suspect most siding with her would stop once they actually need to carve into their own way of life. I've seen many environmentalist types care about the environment so long as it is not directly impacting theirs... It makes it easy to evangelize while being on the absolute upper crust of humanity.

Well, here's a different side of the coin - how many 16 year old suicide bombers are doing that of their own free will? Could a system of beliefs expected to lead to that end state be called 'indoctrination'?

That's exactly my point.
