Toxicity in games.

So a while back maybe a solid week or two I came across an article and in said article RIOT claimed that their tribunal system has done amazing things such as lowering negativity in games and being like a toxic person rehab essentially because once they were banned 90% of players no longer had offenses from there on afterwards and how the system has lowered toxicity in games to a mere 2%, but how come I find a toxic person in every game, why do I always find afk's, ragers, ping spammers, people on tilt, matching up with people who just played together and already raging at each other in champ select. In short at least one person in all of my games seems to be on tilt except me, and no matter what I seem to do ITS EVERY GAME, this is really just going to be the first game I'm going to shelf because of the community. Honestly speaking the 2% of games that have toxicity in them I must be in everyone because this is just ruining the game for me, I try to stay positive and try to keep everyone calm giving out good jobs and Its not getting better the more I play the more I find toxic people, Is anyone else having this problem because its ruining the game for me.

Edit: Link to my other post just so people know im not pulling the 2% out of the air, contains article. http://boards.na.leagueoflegends.com/en/c/miscellaneous/OXsJAeb6-toxic-players-and-player-support-tickets
