Why does an insult from a kid on the internet even bother you? You can't say that it doesn't either, after all, you are taking the time to report said kid.
For starters : Why does an insult from anyone ever bother you?
Secondly: It's not even necessarily a "kid"
Third: I want to play my games to relax, enjoy a community, or for some competition and maybe even some constructive tips on how to play if I can't seem to pull off a win.
Lastly: I know I have been bothered by insults and such online before, generally it means I was having a bad day, or that the person was being particularly mean and nasty towards even his 'teamates'....while I know some people feel that doing things 'online' means that it's "not real"...It can be just as real as texting your gal, or talking to someone on the phone, and of course it can be insulting....Disrespecting people in general does not promote a good atmosphere, it's often someone who is disatisfied with things in thier own life or who gets a hard on from stealing the pleasure or enjoyment of others, even those whom like to make other people angry because they're 'too stupid to realize the joke' or 'oblivious to the fact that they're being manipulated'.
It's easy to manipulate people, it's harder to communicate with them. (Just makes me think of the Dark/Light side of the force)
