He still has much to learn and experience. Most likely, everyone replying to him are more than 5 years older than him which in turn makes it look like a bunch of more learnt older individuals shouting at a child about how he is wrong.
but hey, it's better to learn these things through discussions on an internet forum than through a terrible misunderstanding that would inevitably come from him trying to apply his ideas in real life
While I'm fairly careful with children who are under the age of twelve or thirteen, once they get in high school and start acting this way, I'm not exactly patient with them, and I don't see any reason why I should be.
Just out of curiosity, if you met a fifteen year old on the street that was spouty off, you would then walk up to him or her and say the same things that people are saying to him now?
Personally, I ignore people that are young and immature with regard to life and life experiences. However, if I want to "teach them a lesson," I certainly don't do it by acting just like they are.
Now if they're older, my reaction is completely different.
"The only time I'm wrong is when I'm questioning myself."
I think the youth is already too pandered to. I've actually had it with this societal idea that kids shouldn't be disciplined or talked to like adults if they want to pretend to be an adult. It's not like he's five and we're telling him to shut up.
No one is telling him to shut up, for that matter, we're just arguing with him.
