We ought to. We don't sentence <18 teenagers to death, or life without parole, when they commit murder. We don't allow them to vote. We don't allow them to consent to sex (yeah yeah, the AOC varies by state, whatever). We don't allow most of them to drive, and when we allow it of the older ones, it's generally under greater restrictions than the rest of the population. We don't allow them to buy guns. We don't allow them to drink.
I'll stop now, but we set these restrictions because teenagers are stupid and we realize it, we expect it, and we know we have to mitigate the risks. It's a stupid thing to call someone a f** when you're 17, but unless you're still doing it when you're 25, I'm not going to hold it against you forever.
