I struggle with the duplicity in all this. People aged 15 have not reached the age of majority. They can't vote, can't buy a bottle of wine, can't drive etc etc. That's because we collectively don't trust their judgement at that age and so can't take their actions as seriously as we would an adult.
Then a child does something we hate and we insist they are treated as if they were at the age of majority. Suddenly the goalposts have shifted.
Is is disingenuous. There are plenty of under 18s who have a better grasp of politics and governance than the majority of adults, but we don't let them vote. There are under 17s who could easily pass a driving test. The are under 18s who would responsibly buy alcohol and take it back to their parents without drinking it. Either we make allowances for all of them, or we keep consistent with our opinion that 15 year-olds who do ill-advised things with all the conviction, bravado and self-determination in the world are still not competent to be held to the same account as an adult.
I'd hate to be a kid now. Everything you do is recorded and analysed, and you have the ever increasing pressure of accountability for your actions. No wonder there's an increase in anxiety. And more likelihood of teenagers running away in spectacular circumstances.
