Are political revolutions really brought about by children under 16? I think there's an argument that these policies push for identifying adults and that that might stifle speaking out, but I don't think any of it would be about stifling uprising from 15 year olds.

And when you speak of governments doing this to stay in power: which governments? All political parties in general? Just typical old-school politicians? Because there's a fairly atypical leader in the US, and there's an atypical rising force in Australia, and so on, and I think their popularity is stronger in older age brackets than aforementioned 15 year old.
