If you are so annoyed by a topic or post of this kind, ignore it. If a person starts insulting and cursing everyone, report it to a moderator. But publicly putting down a person for no reason will not achieve anything good. It will only spoil your nerves and his, and you will waste precious time arguing with each other.
Emperor, this is just funny. Grown men and women, as well as teenagers and young people, are trying to explain something to a little boy.
Do you think you will correct him this way? It would be much better if one of you took him under your wing, explained to him how to behave, and told him about the culture of communication on forums.
You know, it's not that difficult to assume such a turn of events... The boy is only 9 years old, while most other forum members are older than 14. Have you ever seen and tried to communicate with a 9-year-old boy? Personally, I wouldn't be able to communicate normally, the age difference is too big.
In general, I suggest remembering one of the favorite characters from domestic cartoons - Leopold the Cat, and simply end the discussion with the pretext of "let's live in peace." The started argument will not lead to anything, no matter how hard you try, everyone will still stick to their opinion. Or do you just want to express yourself?
Where do we end up when we save the world?
