Getting real tired of playing "League of Blame"

The amount of toxic players in this community is just too much. In almost every recent match I've had, someone feels that it is far more important to complain about a mistake someone made then focusing on the game. Majority of those games could have been won had the toxic teamate(s) stopped picking fights the ENTIRE time. It feels like all the time and effort put into this game have been completely wasted, not only could I have been using that time for something far more productive, I probably could have had more fun not fighting with overconfident brats who have made League the hostile community that every ranked match is. If Riot does not crack down harder on those who cannot calmly deal with in-game problems, I will not regret uninstalling and spending my time and money on something with a less bitter feel to it. Most likely the WoW expansion lol. I used to have so much fun playing this game, but all those people who think they have the right to insult and belittle others are quickly destroying this experience for me everyday.
