I think most of the time the trash talking is funny, but some times it goes way over the line. As far as not using a certain weapon based on how you would like to play, well that is up to the person playing the game. For example I hated the Famas in bo because how easy it was to use and how everyone used either that or the ak74u so I hardly ever used it. I don't like using the acr in mw3 for the same reason. That is my call.
