I’m way over 20 and I wholeheartly disagree with you. It is indeed complicated to educate rebelling teenagers but many adults look down on children, teens and young adults just because of them being younger. That is an acceptable behavior.
Even when struggling to educate someone, it’s not ok to treat someone like they are worth nothing. Younger human are human being and deserve to be treated as so.
