You honestly can't get offended by EVERYTHING in a video game, right?
Boards are filled with QQ threads ranging from saying "GG EZ" after a win to "taking advantage of a 4v5 and thereby making me sad".
Enough is enough guys. The millions of people playing league didn't log in to make you happy and it isn't really their fault if you get ruffled by every little thing they do. If someone is going out of their way to be offensive, then report them, but stop acting like trash talk in a video game is a crime against humanity.
Sometimes i truly fear for the future when i see so many that are legitimately offended by such minor disturbances in a VIDEO GAME.
