"Random thought, why is noob an insult? It doesn’t even sound harsh and there is no way to say it to make is sound harsh. It sounds so.... weak in my opinion. But this doesn't mean I don't know the meaning of noob, I know full well what it means."

You might, but other people don't. The general meaning of noob these days has twisted into a shorthand version of, "You're shit at this game! GTFO and get lost!" or something to that effect. That's the impression I get.
