Bullying exists in every game, so it´s not exclusive to Destiny... but still I feel sorry that you have to experience this. As others have posted, some kids your age (and younger!) can be insanely good. My only problem is that, in general, kids tend to be more aggressive towards other fellow players who may not be doing as well as expected. The one time that someone went all out against someone in the Crota raid was clearly a kid, and we were all asking him to stop.
