The league community

I think the league community is getting more and more un-sportsmanlike I cant believe that in a group of ten random strangers just trying to have fun 7 out of the ten jut want to talk non sense all game I was just in an URF match I ended up solo top as ez against another ez and eve for no reason and ez would just poke me and eve would just dive me there was nothing I could do to get away and I kept pinging for help half the enemy team continues to verbally berate me along with my entire team saying things that really don't need to be said it got to the point where I wasn't having fun (not because I was dying over and over but because everyone was doing nothing but saying rude things to or about me) so I left the game and it is absurd that 7 out of ten people can make playing something that is supposed to be fun terrible and because I got sick of all them talking I left I am going to be the punished person. I know there is a mute button but seriously whats the point of playing a game where my team won't work with me on top of all the bad mouthing.
